Example of creating a web hook via atlassian-connect-spring-boot

[el_moreno]

I am trying to create a web hook programmatically using atlassian-connect-spring-boot. In the documentation, the following is specified:

@Autowired
private AtlassianHostRestClients atlassianHostRestClients;

public void doSomething() {
    atlassianHostRestClients.authenticatedAsAddon().getForObject("/rest/api/example", Void.class);
}

I changed it to postForOject as the creation of a web hook is a POST  but I get a 400 Bad Request, which I guess means the payload I am passing is wrong but I get no other details, my payload is as follows (Apologies about the format), which I found here

{
"url": "https://your-app.example.com/webhook-received",
"webhooks": [
{
"events": [
"jira:issue_created",
"jira:issue_updated"
],
"fieldIdsFilter": [
"summary",
"customfield_10029"
],
"jqlFilter": "project = PROJ"
},
{
"events": [
"jira:issue_deleted"
],
"jqlFilter": "project IN (PROJ, EXP) AND status = done"
},
{
"events": [
"issue_property_set"
],
"issuePropertyKeysFilter": [
"my-issue-property-key"
],
"jqlFilter": "project = PROJ"
}
]
}

I have also tried doing:

atlassianHostRestClients.authenticatedAsAddon(AddonAuthenticationType.OAUTH2).getForObject("/rest/api/example", Void.class);

 

and for this one I get a 401.

So, any example out there on how to create a dynamic web hook using atlassian-connect-spring-boot?!?!?! I have looked in the documentation and online and nothing and this has been blocking me for days now. Any help would be appreciated!
