Like the title describes, i can't seem to figure out how to upload a local image and have it posted as a message in slack
Currently i am able to post text messages to slack without issue using the webhook url and axios post seen here:
const res = await axios.post(url, {
text: 'Screenshot',
channel: channelid
}, {
headers: {
authorization: `Bearer ${token}`
}
});
Heres the part of the script that isnt working:
try {
const result = await client.files.upload({
channels: channelid,
initial_comment: "this is the image",
file: fs.createReadStream(fileName)
});
console.log(result);
} catch (error) {
console.error(error);
}
I dont understand how the channelid works in one and not the other.
Calling a method with an xoxb or xoxp token is different than posting a message with a webhook. When you create the webhook on the Slack Developer settings site, you are asked to choose a channel. The webhook will be able to post into that channel without your app being a channel member. When using the xoxb token your bot needs to be a member of the channel that's being passed in the API call. If it's not a member you can expect a channel_not_found or not_in_channel error.
