Requests

Encryption

All requests must be sent using HTTPS with TLS 1.2 or higher. Please make sure your developer tools support this version of TLS as older versions or SSL are not supported for security reasons.

Headers

All Copper API calls must include the following headers to authenticate the request:

Key	Value
X-PW-AccessToken	API Key
X-PW-Application	developer_api
X-PW-UserEmail	Email address of token owner
Content-Type	application/json

Body

For PUT or POST requests (e.g. create, update, search), the request parameters must be provided as JSON in the request body.

Rate limits

All API calls are limited to 180 requests every minute. Once this limit has been reached, calls will return and error with status code 429. This rate limit is evaluated on a rolling window basis.
