I want to post the message from external API as a user using the webhook mentioned in the slack app tab (Incoming Webhook) but when I try, the message print on slack chat place as it sent by the bot itself and does not get any reply of that text as well. How can I post messages using webhook as a specific user, not as a bot?
Following is the line of code to post messages. xmlhttp.open(‘POST’,‘https://hooks.slack.com/services/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’, true)
