Supported Content Types & Limitations

The table below shows the supported content types for the contentType parameter (mentioned in the Send one or more messages and Upload media file for One API sections of the API Reference page) and their size limits.

Note that the size limit with the lowest value between the WhatsApp size limit and the Clickatell API limit will apply. For example. the size limit for an image is 5MB (see table below) - WhatsApp will not accept an image above 5MB even though the Clickatell API can accept a larger media/template media message request.
