# Integrations
Integrations allow you to integrate GitLab with other applications. They
are a bit like plugins in that they allow a lot of freedom in adding
functionality to GitLab.
## Accessing integrations
You can find the available integrations under your project's
**Settings ➔ Integrations** page.
There are more than 20 integrations to integrate with. Click on the one that you
want to configure.

## Push hooks limit
> [Introduced](https://gitlab.com/gitlab-org/gitlab/-/merge_requests/17874) in GitLab 12.4.
If a single push includes changes to more than three branches or tags, services
2021-02-22 17:27:13 +05:30
supported by `push_hooks` and `tag_push_hooks` events aren't executed.
2020-04-22 19:07:51 +05:30
The number of branches or tags supported can be changed via
[`push_event_hooks_limit` application setting ](../../../api/settings.md#list-of-settings-that-can-be-accessed-via-api-calls ).

## Service templates
2020-04-22 19:07:51 +05:30
2020-10-24 23:57:45 +05:30
Service templates are a way to set predefined values for a project integration across
2020-07-28 23:09:34 +05:30
all new projects on the instance.
2020-04-22 19:07:51 +05:30
2020-10-24 23:57:45 +05:30
Read more about [Service templates ](services_templates.md ).
## Project integration management
2020-11-24 15:15:51 +05:30
Project integration management lets you control integration settings across all projects
2020-10-24 23:57:45 +05:30
of an instance. On the project level, administrators you can choose whether to inherit the
2020-11-24 15:15:51 +05:30
instance configuration or provide custom settings.
2020-10-24 23:57:45 +05:30
Read more about [Project integration management ](../../admin_area/settings/project_integration_management.md ).

## Troubleshooting integrations
2020-07-28 23:09:34 +05:30
Some integrations use service hooks for integration with external applications. To confirm which ones use service hooks, see the [integrations listing ](#integrations-listing ) above. GitLab stores details of service hook requests made within the last 2 days. To view details of the requests, go to that integration's configuration page.
2020-04-22 19:07:51 +05:30
The **Recent Deliveries** section lists the details of each request made within the last 2 days:
- HTTP status code (green for 200-299 codes, red for the others, `internal error` for failed deliveries)
- Triggered event
- URL to which the request was sent
- Elapsed time of the request
- Relative time in which the request was made
To view more information about the request's execution, click the respective **View details** link.
2020-07-28 23:09:34 +05:30
On the details page, you can see the request headers and body sent and received by GitLab.
2020-04-22 19:07:51 +05:30
2020-07-28 23:09:34 +05:30
To repeat a delivery using the same data, click **Resend Request** .
2020-04-22 19:07:51 +05:30
2020-05-24 23:13:21 +05:30
### Uninitialized repositories
Some integrations fail with an error `Test Failed. Save Anyway` when you attempt to set them up on
2020-07-28 23:09:34 +05:30
uninitialized repositories. Some integrations use push data to build the test payload,
and this error occurs when no push events exist in the project yet.
2020-05-24 23:13:21 +05:30
To resolve this error, initialize the repository by pushing a test file to the project and set up
the integration again.
2020-04-22 19:07:51 +05:30
## Contributing to integrations
Because GitLab is open source we can ship with the code and tests for all
plugins. This allows the community to keep the plugins up to date so that they
always work in newer GitLab versions.
For an overview of what integrations are available, please see the
2020-05-24 23:13:21 +05:30
[project_services source directory ](https://gitlab.com/gitlab-org/gitlab/tree/master/app/models/project_services ).

Contributions are welcome!
