There are two modes in sending texts yourself: Concurrent and Fast.

❯❯❯❯ Concurrent mode requires 2 API calls to send a message and all contacts must be imported beforehand:

Ask the system via /api/message/next for the next contact in a project, this call makes sure only one contact is returned at any time to avoid duplicate texts and allowing many texters to send the same project at the same time.
Use the data from the previous call to actually send the message using /api/message/send. This call schedules the text for delivery or returns an error if delivery is not possible.

🏎️💨 Fast mode requires only one API call and no contacts required to be imported.

This mode assumes you have the list of contacts and ability to go over that list. ！This mode can be used if authorized only, submit a ticket to our support team to enable it for your account.

Fast mode you pull a contact phone from your list and send it by using /api/message/send.

New contacts will be created in our system automatically, for already existing contacts all tags will be honored as usual, i.e. dnd tags will be skipped.

All responses will be tagged in our system, to sync with your database use our Webhooks.
