Response format

​
202 — Accepted

Returned when at least one user passes validation. The response includes counts and any per-user errors. 
{
  "trace_id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "users_accepted": 2,
  "users_rejected": 1,
  "errors": [
    {
      "userIndex": 2,
      "message": "at least one identifier is required (user_id, email, phone_number, or anon_id)"
    }
  ]
}

​
400 — Bad Request

Returned when the payload is invalid or all users fail validation. 
{
  "error": "validation failed",
  "trace_id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890",
  "errors": [
    {
      "userIndex": 0,
      "message": "events array is required and must not be empty"
    }
  ]
}

​
401 — Unauthorized

Returned when the API key is missing, invalid, or the x-customer-id header is absent. 
{
  "error": "unauthorized"
}

​
413 — Payload Too Large

Returned when the request body exceeds 10 MB.

​
503 — Service Unavailable

Returned when the service is temporarily unable to process requests. Retry with exponential backoff. 
{
  "error": "service temporarily unavailable",
  "trace_id": "a1b2c3d4-e5f6-7890-abcd-ef1234567890"
}

​
Partial acceptance

The Events API uses partial acceptance: valid users are processed even if other users in the same request fail validation. This means a single request can return 202 Accepted with both users_accepted > 0 and users_rejected > 0.
Always check the users_rejected field in the response. If it is greater than zero, inspect the errors array to understand which users failed and why.

​
Trace ID

Every response includes a trace_id. This unique identifier can be used to:
  • Correlate requests with RevBridge support for debugging
  • Log and track requests in your own systems
  • Match accepted events to their downstream effects
Store the trace_id from every API response in your logs. It significantly speeds up troubleshooting.

​
Batch request — multiple users

Send events for multiple users in a single request for better performance. 
{
  "users": [
    {
      "identifiers": { "email": "jane@example.com", "user_id": "usr_001" },
      "events": [
        { "event_name": "purchase", "revenue": 49.99, "currency": "USD" }
      ]
    },
    {
      "identifiers": { "email": "john@example.com", "user_id": "usr_002" },
      "events": [
        { "event_name": "add_to_cart", "product_id": "SKU-123", "product_name": "Blue T-Shirt" }
      ]
    },
    {
      "identifiers": { "phone_number": "+5511999887766" },
      "events": [
        { "event_name": "page_view", "page": "/summer-sale" },
        { "event_name": "product_view", "product_id": "SKU-456" }
      ]
    }
  ]
}

​
Multiple events per user

A single user can have multiple events in one request. This is useful for sending a batch of historical events. 
{
  "users": [
    {
      "identifiers": {
        "user_id": "usr_001",
        "email": "jane@example.com",
        "first_name": "Jane",
        "city": "São Paulo",
        "country": "BR"
      },
      "events": [
        {
          "event_name": "product_view",
          "timestamp": "2026-01-15T14:00:00Z",
          "product_id": "SKU-789",
          "category": "shoes"
        },
        {
          "event_name": "add_to_cart",
          "timestamp": "2026-01-15T14:05:00Z",
          "product_id": "SKU-789",
          "quantity": 1
        },
        {
          "event_name": "purchase",
          "timestamp": "2026-01-15T14:10:00Z",
          "revenue": 129.90,
          "currency": "BRL",
          "order_id": "ORD-5432"
        }
      ]
    }
  ]
}

​
Custom event properties

Any key-value pairs beyond the standard fields are stored as custom event properties. 
{
  "users": [
    {
      "identifiers": { "user_id": "usr_001" },
      "events": [
        {
          "event_name": "subscription_changed",
          "plan": "pro",
          "billing_cycle": "annual",
