+## Credentials
+
+`DADATA_API_KEY` and `DADATA_SECRET_KEY` environment variables are used by default to authenticate client.
+
+Custom credential provider may be used by implementing `client.CredentialProvider` interface.
+
+Also, there is a "simple" credential provider `client.Credentials` you may utilize.
+
+```go
+creds := client.Credentials{
+    ApiKeyValue:    "<YOUR_API_KEY>",
+    SecretKeyValue: "<YOUR_SECRET_KEY>",
+}
+
+api := NewSuggestApi(client.WithCredentialProvider(&creds))
