Send Message

The response contains a messageid per receiver, which you can use to track the message afterwards via Get message by ID (GET /v1/message/{messageid}).

Instead of writing the text in message you can pass template with the ID of one of your Message Templates (preferably the public ID tpl_...). The text of the template is then used as the message and personalisation placeholders such as [FIRSTNAME] are filled in per receiver. When both message and template are sent, the template wins and the response contains a warnings entry. This also works for Send message to group and Send voice message.

Base URL:

POST: https://api.smsgatewayapi.com/v1/message/send

Parameter	Input	Description
client_id	API client ID	Developer › API & Webhooks › API credentials	Required

message	message	the message to be sent. Not required when `template` is given; when both are sent, the template wins	Partial
template	message template ID	The ID of one of your message templates, preferably the public ID (tpl_...); the numeric ID is accepted too. The text of the template is used as the message and personalisation placeholders such as [FIRSTNAME] are filled in. When message is sent as well it is ignored and the response contains a warnings entry. An unknown ID, or a template that is not yours, returns error 150. A template that has an attachment (see Get message templates) cannot be sent as SMS or voice and returns error 169; send it with the WhatsApp endpoints instead.

Exceptions:

Our system processes the messages in UTF8 and generates this in GSM unicode. There are 9 characters that are counted as 2 characters in GSM unicode. If you use one of these characters in your message, your message will be longer. Example: If you have a message of 160 characters and you used a €-characters then the message real length is 161 characters long
