# Client API

> API documentation for Edesy Email client endpoints including user identification, device registration, and event tracking.

Source: https://edesy.in/docs/email-platform/api/client

This is the documentation for our ingestion API's which are used by our client SDKs. They can be used to create additional clients or ingest data without a secret key.

## Authentication
Authentication to client endpoints is handled via public bearer API keys. These API keys allow for ingestion only of data and only on select endpoints. You can generate a new public key at any time in the portal and we recommend using a separate key per platform.

To authenticate requests, set the `Authorization` header to be `Bearer YOUR_KEY` where `YOUR_KEY` is the API key you generated.

#### Example
```json
{
    "Authorization": "Bearer pk_dbf68c87-e579-4dac-b083-77fed0294e67"
}
```
