Turn on texting
Turns texting on for a phone number, or re-reads where it stands. A US number delivers no texts until carriers approve the business: while texting is registering, send the owner sms_registration_url, a form for the business’s legal details (valid 7 days). Texting becomes active on approval. Then set answer_texts, text_back_missed_calls and text_new_leads with PATCH /v1/phone-numbers/.
