Live request

Request builder

Your key is sent to the gateway with this request and is never stored. A key is shown once, when it is created or rotated — manage keys in your workspace.

This endpoint does not accept a request body.

Sending calls the gateway for real: it authenticates your key, counts the request against your plan, and returns whatever the provider returns.

curl --request GET 'https://gateway.payloadapi.com/phone-number-checker-api/v1/api/v1/phonevalidation' --header "Authorization: Bearer $PAYLOADAPI_KEY" --header 'Content-Type: application/json' --header 'X-Payload-Trace: enabled'
