Authorizations

​
Authorization
string
header
required

Use your API key as the Bearer token. You can view your API key and secret in your Zenzap organization API key settings.

​
X-Signature
string
header
required

HMAC-SHA256 signature for request verification.

Headers

​
X-Signature
string
required

HMAC signature of the request.

The signature payload differs by HTTP method:

  • POST/PUT/PATCH/DELETE: HMAC-SHA256 of the request body
  • GET: HMAC-SHA256 of the full request URI (path + query string)

The signature is calculated as:

  1. Determine the payload:
    • For POST/PUT/PATCH/DELETE: Use the request body
    • For GET: Use the full request URI (e.g., /v2/members?limit=10&offset=0)
  2. Calculate HMAC-SHA256 of the payload using your API secret
  3. Hex-encode the output

Example for GET request to /v2/members?limit=10:

payload = "/v2/members?limit=10"
signature = HMAC-SHA256(secret, payload)
X-Signature: hex(signature)

Example for POST request with body {"topicId":"123","text":"Hello"}:

payload = '{"topicId":"123","text":"Hello"}'
signature = HMAC-SHA256(secret, payload)
X-Signature: hex(signature)
Example:

"a3d5f8e7c2b1d4f6a8e9c7b5d3f1a2e4b6c8d0f2e4a6b8c0d2e4f6a8b0c2d4e6"
