# Get Whitelist Status

GET https://api.pinnacle.sh/rcs/test/agents/{agentId}/numbers

Check the current whitelist status of a phone number for a specific test agent.Use this endpoint to poll the status of a previously whitelisted number and determine
whether the recipient has accepted or rejected the tester invite.## Status Values- **`PENDING`** — The tester invite was sent but the recipient has not yet responded. Ask the recipient to check their messages and accept the invite.
- **`ACCEPTED`** — The recipient accepted the invite. Messages can be exchanged.
- **`REJECTED`** — The recipient rejected the invite or the invite could not be delivered since the carrier does not support test agents. If the user rejected the invite, they can accept it again by tapping "Make me a tester" in the same message from "RBM Tester Management".Accepting the inviteDeclining the invite
