Available tools 3

Read directly from the server with tools/list, grouped by what they act on. If a tool disappears, we record the date.

regi

regi_list_phone_numbers

List the WhatsApp Business phone numbers of the Regi account. Each `id` is the phoneNumberId that regi_send_template needs. Use this first when you do not know the phoneNumberId.

regi_list_templates

List the WhatsApp message templates of the Regi account with name, language, category and status. Only templates with status APPROVED can be sent. The componentsJson field shows how many {{n}} variables the body expects.

regi_send_template

Send one approved WhatsApp template to one recipient. This bills per message and reaches a real person. Regi blocks a second send of a template to the same recipient within 2 hours until the recipient replies (HTTP 400); this tool does not bypass that block. Values in body_parameters fill {{1}}, {{2}}, … in order.
