Even when I pass either the to_contact OR to_channel OR both, I get the same response. Your help would be greatly appreciated,

Thanks for reaching out to the Zoom Developer Forum and welcome to our community.
Please allow me some time to do some testing on my end and I will come back with an update shortly.

Hi Elisa

Any feedback on this? I have been delayed now for 3 days on my integration?

Your input and support on this would be greatly appreciated,
Thx

Hi @tiaan.schulz
Thank you for your patience.
I am not able to replicate this behavior on my end.
I am able to send a message either to a channel or directly to a contact.

Here is the request body I am sending:

{
“message”: “Hello this is a test and it is working”,
“to_contact” : “elisa@mail.com”,
“at_items” : [
{
“at_contact”: “elisa@mail.com”,
“at_type” : 1,
“end_position” : 8,
“start_position” : 0
}
],
“rich_text” : [
{
“start_position” : 0,
“end_position” : 1,
“format_type” : “Paragraph”,
“format_attr” : “h1”
}
]
}

If I change the to_contact for to_channel, I send the message to a channel instead of directly to the contact.

Could you make sure that you are passing the same email address on the fields “to_conatc” and “at_contact” ?

Hi Elisa

Please ignore my message. I deleted my collection in Postman and re-imported.

Tried then using API call provided there and now seems to work without any issues. Will keep trying and revert if anything changes…
