Sendify API overview

Sendify provides RESTful APIs for campaigns and contact management. After creating an API Key, call /v2/me to verify the key and account before using business APIs. Current documentation version: 1.0.0-beta

To query Sendify data from Codex, Cursor, or Claude in natural language, see Sendify MCP. MCP is currently read-only.

Base URL

https://api.sendify.dingstore.cn

Use HTTPS for every request and send the API Key as a Bearer token in the Authorization header.

1. Create an API Key

In the Sendify console, open Open Capabilities / API Keys / Create key.

The full API Key is displayed only once. Save it immediately in a secure secret-management system.

2. Verify the API Key

curl -X GET \
  "https://api.sendify.dingstore.cn/v2/me" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Accept: application/json"

An HTTP 200 response containing account information confirms that the key is valid.

Never store an API Key in browser code, a public repository, logs, or an end-user environment. Production requests should come from a backend service.

3. Make an API request

For example, create a minimal contact:

curl -X POST \
  "https://api.sendify.dingstore.cn/dmx/v2/contacts" \
  -H "Authorization: Bearer YOUR_API_KEY" \
  -H "Content-Type: application/json" \
  -d '{"email":"customer@example.com"}'

4. Handle errors and rate limits

HTTP status	Meaning	Recommended action
`401`	Missing or invalid API Key	Check the `Authorization` header and key status
`403`	The key lacks API access	Check key permissions
`429`	Rate limit exceeded	Wait and retry with exponential backoff

For bulk synchronization, queue work, limit retries, and log the endpoint, HTTP status, and relevant object ID.

5. Protect API Keys

Use separate keys for development, staging, and production.
Grant the minimum required permissions.
Revoke and replace keys after personnel changes or suspected exposure.
Do not use a production key for local or shared testing.
