HTTP V2 API

Use the HTTP V2 API to send data directly from your server to the HTTP V2 endpoint.

The HTTP V2 API replaces the deprecated HTTP API.

Authentication

This API uses your API key passed in the body of the request:

api-key=API_KEY

For more information, see Find your API Credentials

Endpoints

Region Endpoint
Standard server https://api2.amplitude.com/2/httpapi
EU residency server https://api.eu.amplitude.com/2/httpapi

Considerations

Keep the following in mind as you use the HTTP V2 API.

Upload limit

For Starter plan customers:

Limit your upload to 100 batches per second and 1000 events per second. You can batch events into an upload, but we recommend not sending more than 10 events per batch. Amplitude expects fewer than 100 batches per second, and the 1000 events per second limit still applies.

For customers on Growth and Enterprise plans:

Keep request sizes under 1 MB with fewer than 2000 events per request. When you exceed these size limits, you get a 413 error.

If you have high volume and concerned with scale, partition your work based on device_id or user_id. This ensures that throttling on a particular device_id (or user_id) doesn't impact all senders in your system. If you use a proxy service to send events to Amplitude, make sure that throttling forwards to your clients, instead of letting spammy clients slow down a partition of work in your system.

Information for partner integrations

If you have an event ingestion integration with Amplitude, you need to send your integration's assigned partner ID in the event payload.

For help finding your integration's partner ID and a payload example, see Create an Event Ingestion Integration.

All-zero device IDs: Limit Ad Tracking enabled

As of iOS 10, Apple replaces the Identifier for Advertiser (IDFA) with all zeros if the user enables Limit Ad Tracking. Because all events require a device ID, Amplitude drops device IDs of all zeros and returns an error on the request.

If you are passing the IDFA as the device ID, first run a check on the IDFA value. If it's all zeros, pass a different value for the device ID, such as the Identifier for Vendor (IDFV).

Windows OS

If you are using a Windows operating system, then you may have to replace all single quotes with escaped double quotes.

String character limit

All string values, like user_id, event, or user property values, have a character limit of 1024 characters.

Set date values

Amplitude compares dates as strings, so it's best to use the ISO 8601 format (YYYY-MM-DDTHH:mm:ss). This format lets you perform date comparisons, (for example: '2016-01-31' > '2016-01-01'). Comparison also works for datetime values in this format (for example: '2017-08-07T10:09:08' > '2017-08-07T01:07:00').

Set time values

You must send the time parameter in each event as millisecond since epoch. Any other format (such as ISO format) results in a 400 Bad Request response.

Event deduplication

It's highly recommended that you send an insert_id for each event to prevent sending duplicate events to Amplitude. Amplitude ignores subsequent events sent with the same insert_id on the same device_id (if the event has a device_id value) in each app within the past 7 days.

Device IDs and User IDs minimum length

Device IDs and User IDs must be strings with a length of 5 characters or more. This is to prevent potential instrumentation issues. If an event contains a device ID or user ID that's too short, the ID value is removed from the event.

Override the default minimum length of 5 characters by passing the min_id_length option with the request.

If the event doesn't have a user_id or device_id value, Amplitude can reject the with a 400 status.

Invalid IDs that result in a 400 error

  • "anonymous"
  • "nil"
  • "none"
  • "null"
  • "n/a"
  • "na"
  • "undefined"
  • "unknown"
  • """"
  • "00000000-0000-0000-0000-000000000000"
  • "{}"
  • "lmy47d"
  • "0"
  • "-1"

Language field

If the language field in the request contains a tag, the tag changes to its human-friendly language name. For example, if a request contains "language": "en-US", it changes to "language": "English" before Amplitude stores it.

The following table shows the list of mappings. Language tags are case-insensitive.

Headers

To send data to Amplitude HTTP V2 API, a Content-Type header must be set to application/json.

Body parameters

Name Description
api_key Required. String. Amplitude project API key.
events Required. []. Array of Events to upload.
options Optional. []. Object.

Event array keys

You can send these keys in the JSON event object. Note that one of user_id or device_id is required, as well as the event_type.

Name
Description
user_id Required if device_id isn't used. String. ID for the user. Must have a minimum length of 5 characters unless overridden with the min_id_length option.
device_id Required if user_id isn't used. String. A device-specific identifier, such as the Identifier for Vendor on iOS. If a device_id isn't sent with the event, then it's set to a hashed version of the user_id.
event_type Required. String. A unique identifier for your event. Amplitude reserves the following event names for internal use: [Amplitude] Start Session", [Amplitude] End Session", [Amplitude] Revenue", [Amplitude] Revenue (Verified)", [Amplitude] Revenue (Unverified)", and [Amplitude] Merged User". Note: $identify and $groupidentify are predefined for identification and group identification.
time Optional. The timestamp of the event in milliseconds since epoch. If time isn't sent with the event, then it's set to the request upload time.
event_properties Optional. Object. A dictionary of key-value pairs that represent data to send along with the event. You can store property values in an array. Date values are transformed into string values. Object depth may not exceed 40 layers.
user_properties Optional. Object. A dictionary of key-value pairs that represent data tied to the user. You can store property values in an array. Date values are transformed into string values. User property operations ($set, $setOnce, $add, $append, $unset) are supported when event_type is $identify. Object depth may not exceed 40 layers.
groups Optional. Object. This feature is available to Growth or Enterprise customers who've purchased the Accounts add-on. This field adds a dictionary of key-value pairs that represent groups of users to the event as an event-level group. You can track up to 5 unique group types and 10 total group values per event. Any groups past that threshold aren't tracked.
group_properties Optional. Object. This feature is available to customers who've purchased the Accounts add-on. When "event_type" is $groupidentify, the field is a dictionary of key-value pairs that represent properties tied to the groups listed in the "groups" field. The field is ignored for other event types. Group property operations ($set, $setOnce, $add, $append, $unset) are also supported.
$skip_user_properties_sync Optional. Boolean. When true user properties aren't synced. Defaults to false.
app_version Optional. String. The current version of your application.
platform Optional. String. Platform of the device.
os_name Optional. String. The name of the mobile operating system or browser that the user is using.
os_version Optional. String. The version of the mobile operating system or browser the user is using.
device_brand Optional. String. The device brand that the user is using.
device_manufacturer Optional. String. The device manufacturer that the user is using.
device_model Optional. String. The device model that the user is using.

region Optional. String. The current region of the user.
city Optional. String. The current city of the user.
dma Optional. String. The current Designated Market Area of the user.
language Optional. String. The language set by the user.
price Optional. Float. The price of the item purchased. Required for revenue data if the revenue field isn't sent. You can use negative values for refunds.
quantity Optional. Integer. The quantity of the item purchased. Defaults to 1 if not specified.
revenue Optional. Float. Revenue = (price x quantity). If you send all 3 fields of price, quantity, and revenue, then the revenue value is (price x quantity). Use negative values for refunds.
productId Optional. String. An identifier for the item purchased. You must send a price and quantity or revenue with this field.
revenueType Optional. String. The type of revenue for the item purchased. You must send a price and quantity or revenue with this field.
location_lat Optional. Float. The current Latitude of the user.
location_lng Optional. Float. The current Longitude of the user.
ip Optional. String. The IP address of the user. Use $remote to use the IP address on the upload request. Amplitude uses the IP address to reverse lookup a user's location (city, country, region, and DMA). Amplitude can drop the location and IP address from events after they reach Amplitude servers. Contact the Support team to configure this.
idfa Optional. String. (iOS) Identifier for Advertiser.
idfv Optional. String. (iOS) Identifier for Vendor.
adid Optional. String. (Android) Google Play Services advertising ID
android_id Optional. String. (Android) Android ID (not the advertising ID)
event_id Optional. Integer. (Optional) An incrementing counter to distinguish events with the same user_id and timestamp from each other. Amplitude recommends you send an event_id, increasing over time, especially if you expect events to occur simultaneously.
session_id Optional. Long. The start time of the session in milliseconds since epoch (Unix Timestamp), necessary if you want to associate events with a particular system. A session_id of -1 is the same as no session_id specified.
insert_id Optional. String. A unique identifier for the event. Amplitude deduplicates subsequent events sent with the same device_id and insert_id within the past 7 days. Amplitude recommends generating a UUID or using some combination of device_id, user_id, event_type, event_id, and time.
plan Optional. Object. Tracking plan properties. Amplitude supports only branch, source, version properties.
plan.branch Optional. String. The tracking plan branch name. For example: "main".
plan.source Optional. String. The tracking plan source. For example: "web".
plan.version Optional. String. The tracking plan version. For example: "1", "15".

Options

Name
Description
min_id_length Optional. Integer. Overrides the default minimum length of 5 for user_id & device_id fields.

Response

Amplitude recommends that you implement retry logic and send an insert_id (used for deduplication of the same event) in your events. This prevents lost events or duplicated events if the API is unavailable or a request fails.

Logging errors

Amplitude recommends that you add your own logging to capture responses that receive a response other than 200.

200

200 OK: Successful real time event upload. If you don't receive a 200 OK response, retry your request.

Name
Description
code Integer. 200 success code
events_ingested Integer. The number of events ingested from the upload request.
payload_size_bytes Integer. The size of the upload request payload in bytes.
server_upload_time Long. The time in milliseconds since epoch (Unix Timestamp) that Amplitude's event servers accepted the upload request.

400

400 Bad Request. A 400 indicates invalid upload request. Check the response for more information.

Possible reasons for an invalid request:

  • The request body isn't valid JSON. The error returned is "Invalid JSON request body".
  • The request body is missing required fields. The error returned is "Request missing required field", and indicates which fields are missing.
  • The events object has invalid fields. events_with_invalid_fields maps field names to the index of the first event that returns an error.
  • Some devices are silenced.

Server Error 500, 502, 504

500, 502, and 504 Server Error. Amplitude encountered an error while handling the request. A request with this response may not have been accepted by Amplitude. If you retry the request, it could duplicate the events. To avoid duplication, send an insert_id in your requests.

503 Service Unavailable

503 Service Unavailable. Request failed because of an internal Amplitude issue. Retrying a request with a 503 response doesn't risk duplicating events.
