The Zapper API uses API keys to authenticate requests.
We authenticate your private API key using HTTP authorization request headers. To learn more about how authorization headers work, check out this documentation on the topic from Mozilla foundation.
Requesting a private key
You will need a private API key to use the Zapper API. To request an API key, please file a ZenDesk ticket. You will be issued a private API key in 24-48 hours.
These private API keys still have a rate limit of 30RPM on the
endpoints and 1,000RPM on ALL endpoints collectively.
If these rate limits are not sufficient, you may also request a higher rate limit for your private API key by via the same ZenDesk ticket link, through replying to it in your email.
Testing endpoints using the API key on Swagger
You can test the available endpoints on Swagger by entering your API key into the Authorize section in Swagger. This will then allow you to see the responses for various endpoints based on parameters you specify.
