How to delete message replies using Slack API? - slack-api

Question

I'm getting an error when I try to use Slack API to remove the replies saying the channel doesn't exists.
To validate it, I'm calling the:
https://slack.com/api/channels.history?token={token}&channel={channel}&count=1&inclusive=true&latest={ts}&oldest={ts}
Then I get the message back.
The message I'm getting back is this one:
{
"ok": true,
"latest": "1540555927.024300",
"oldest": "1540555927.024300",
"messages": [
{
"text": "This message was deleted.",
"edited": {
"user": "UD6SLKGEP",
"ts": "1540555928.000000"
},
"type": "message",
"subtype": "tombstone",
"user": "USLACKBOT",
"hidden": true,
"thread_ts": "1540555927.024300",
"reply_count": 1,
"replies": [
{
"user": "UD6SLKGEP",
"ts": "1540555928.024401"
}
],
"subscribed": false,
"unread_count": 1,
"ts": "1540555927.024300"
}
],
"has_more": false,
"is_limited": true
}
As you can see, there is this "This message was deleted." that seems to be generated automatically and keep showing up because I still have replies associated to it.
If I call the same endpoint passing the reply ts (1540555928.024401), for the same channel I get this:
{
"ok": true,
"latest": "1540555928.024401",
"oldest": "1540555928.024401",
"messages": [
{
"type": "message",
"user": "UD6SLKGEP",
"text": "45d7bc14a6fa03 23456789 abcdefghijklmnop",
"bot_id": "BD6AJUY8G",
"thread_ts": "1540555927.024300",
"ts": "1540555928.024401"
}
],
"has_more": false,
"is_limited": true
}
Which means that there is a message there, which is a reply from another message.
The problem starts when I try to remove this reply message.
I call this endpoint:
https://slack.com/api/chat.delete?token={token}
Passing the channel and the reply ts as the payload:
{
"channel": "CD65XB2D7",
"message_ts": "1540555928.024401"
}
Now instead of having the message removed, I get this response:
{
"ok": false,
"error": "channel_not_found",
"warning": "missing_charset",
"response_metadata": {
"warnings": [
"missing_charset"
]
}
}
But the channel exists and I'm using it to remove other messages as well. That happens when I try to remove the reply from a message only.
Is there something special about removing reply messages?

I just found out the problem here:
https://api.slack.com/changelog/2017-10-keeping-up-with-the-jsons#methods
For some reason on my side it's working for messages, but not for replies. I had to move the token to the "Authorization" on header with the Bearer as suggested on this link.
