The new platform API at Clickatell seems to not allow you to add "from" to the JSON payload, complaining that it not a 2 way integration, but the is no possibility to add a text moniker to the short codes so that instead of the number "COMPANY" would appear
This is possible with the older api. Clickatell endpoints, and wondering if anyone can confirm that this functionality is actually removed, but better still suggest a workaround if it is
The Platform account doesn't have the sender ID feature - however, the FROM parameter is still available for any two-way integration with an active two-way subscription. The subscription can either be for a short code or a long number, if specified in the message submission. If the feature is supported by suppliers and network operators, these messages will deliver with the short code or long number specified.
