How can I create issues using REST API nowadays?

Question

Hi everyone,

I'm developing a solution that needs to trigger the creation of a work item through the REST API in a team-managed software project.
However, even though I'm an ORG ADMIN, I'm receiving an "Unauthorized" response and can't perform this action using the API token I created specifically for this solution.

Has anyone experienced something similar? Am I missing any additional permissions or specific configurations for team-managed projects?

Thanks in advance for your help!

## Code

function onFormSubmit(e) {

Logger.log(JSON.stringify(e.namedValues));

const JIRA_API_TOKEN = PropertiesService.getScriptProperties().getProperty('JIRA_API_TOKEN');

const JIRA_EMAIL = PropertiesService.getScriptProperties().getProperty('JIRA_EMAIL');

const jiraUrl = "https://gazeus.atlassian.net/rest/api/3/issue";

const jiraAuth = "Basic " + Utilities.base64Encode(JIRA_EMAIL + ":" + JIRA_API_TOKEN);

const values = e.namedValues;

const managerEmail = getFieldValue(values, "Manager Email");

const managerAccountId = getUserAccountIdByEmail(managerEmail, jiraAuth);

const payload = buildJiraPayload(values, managerAccountId);

const options = {

method: "POST",

contentType: "application/json",

headers: { "Authorization": jiraAuth },

payload: JSON.stringify(payload),

muteHttpExceptions: true

};

const response = UrlFetchApp.fetch(jiraUrl, options);

Logger.log(`Status: ${response.getResponseCode()}`);

Logger.log(`Response: ${response.getContentText()}`);

}

## Payload Example:

```
{
"fields": {
"project": {
"key": "ONBOARDING"

"issuetype": {

It does look like an authentication issue though. I like to use Postman to break it down and troubleshoot step by step. (Can I get the authentication to work for a simple GET, then try the POST, ...) You could also try to log the jiraAuth string to make sure it is correct...

But I can't really spot your problem I'm afraid... :-)
I hope a community member that has experienced this can provide more insight!

The API token was created with my credentials, and I am an ORG administrator, and I am also part of the project users with administrator permissions. In theory, I should have this kind of permission. I don't know why, through the web interface, I can and through the REST API, I can't.

You do not have permission to create issues in this project.

Makes make think you need to check if the reporter has 'Create issues' permission in the target project. Who is the creator of the issue? Perhaps it needs to be defined explicitly?

(An alternative to a solution like this can be to use native Jira features like a public form or an issue collector)
