Batch Single Push API

Function Description

Used for batch single push notifications, allowing multiple target users to receive pushes in one call. Supports pushing via registration_id or alias:

Push via registration_id: POST /v4/batch/push/regid
Push via alias: POST /v4/batch/push/alias
Capability Limits:
- Maximum 500 push targets per request
- Supports concurrent processing for efficiency
- Returns partial success results during rate limiting
- This API and the Push API share the same QPS quota. Using the batch push API to push 1 regid or 1 alias consumes 1 QPS quota of the Push API.

Authentication

Add authentication field in HTTP Header:

Authorization: Basic ${base64_auth_string}

              
              Authorization: Basic ${base64_auth_string}

Notes

Rate Limit Handling: Returns partial success results during rate limiting (msg_id for succeeded + error for failed).
Duplicate Check: All targetor cid values must be unique within a batch.
Quantity Limit: Maximum 500 targets per request.
Error Handling: Global errors (e.g. auth failure) immediately terminate without partial results.
