Authentication

You'll need to authenticate your requests to access any of the endpoints in the K-LINK API. In this guide, we'll look at how authentication works. K-LINK offers two ways to authenticate your API requests: Basic authentication and OAuth2 with a token — OAuth2 is the recommended way.

OAuth2 with bearer token

The recommended way to authenticate with the K-LINK API is by using OAuth2. When establishing a connection using OAuth2, you will need your access token — you will find it in the K-LINK dashboard under API settings. Here's how to add the token to the request header using cURL:

curl https://api.klink.cloud/api/v1/contacts \
  -H "Authorization: Bearer {token}"

Always keep your token safe and reset it if you suspect it has been compromised.
