APPLIES TO: Developer | Basic | Standard | Premium

Each API Management service instance maintains a configuration database that contains information about the configuration and metadata for the service instance. Changes can be made to the service instance by changing a setting in the Azure portal, using Azure tools such as Azure PowerShell or the Azure CLI, or making a REST API call. In addition to these methods, you can manage your service instance configuration using Git, enabling scenarios such as:

Configuration versioning - Download and store different versions of your service configuration
Bulk configuration changes - Make changes to multiple parts of your service configuration in your local repository and integrate the changes back to the server with a single operation
Familiar Git toolchain and workflow - Use the Git tooling and workflows that you are already familiar with

The following diagram shows an overview of the different ways to configure your API Management service instance.

When you make changes to your service using the Azure portal, Azure tools such as Azure PowerShell or the Azure CLI, or the REST API, you're managing your service configuration database using the https://{name}.management.azure-api.net endpoint, as shown on the right side of the diagram. The left side of the diagram illustrates how you can manage your service configuration using Git and Git repository for your service located at https://{name}.scm.azure-api.net.

The following steps provide an overview of managing your API Management service instance using Git.

Access Git configuration in your service
Save your service configuration database to your Git repository
Clone the Git repo to your local machine
Pull the latest repo down to your local machine, and commit and push changes back to your repo
Deploy the changes from your repo into your service configuration database

This article describes how to enable and use Git to manage your service configuration and provides a reference for the files and folders in the Git repository.

Important

This feature is designed to work with small to medium API Management service configurations, such as those with an exported size less than 10 MB, or with fewer than 10,000 entities. Services with a large number of entities (products, APIs, operations, schemas, and so on) may experience unexpected failures when processing Git commands. If you encounter such failures, please reduce the size of your service configuration and try again. Contact Azure Support if you need assistance.

Access Git configuration in your service

Navigate to your API Management instance in the Azure portal.
In the left menu, under Deployment and infrastructure, select Repository.

Save the service configuration to the Git repository

Caution

Any secrets that are not defined as named values will be stored in the repository and will remain in its history. Named values provide a secure place to manage constant string values, including secrets, across all API configuration and policies, so you don't have to store them directly in your policy statements. For more information, see Use named values in Azure API Management policies.

Before cloning the repository, save the current state of the service configuration to the repository.

On the Repository page, select Save to repository.
Make any desired changes on the confirmation screen, such as the name of the branch for saving the configuration, and select Save.

After a few moments the configuration is saved, and the configuration status of the repository is displayed, including the date and time of the last configuration change and the last synchronization between the service configuration and the repository.

Once the configuration is saved to the repository, it can be cloned.

For information on saving the service configuration using the REST API, see Tenant configuration - Save.

Get access credentials

To clone a repository, in addition to the URL to your repository, your need a username and a password.

On the Repository page, select Access credentials near the top of the page.
Note the username provided on the Access credentials page.
To generate a password, first ensure that the Expiry is set to the desired expiration date and time, and then select Generate.

Important

Make a note of this password. Once you leave this page the password will not be displayed again.

Clone the repository to your local machine

The following examples use the Git Bash tool from Git for Windows but you can use any Git tool that you're familiar with.

Open your Git tool in the desired folder and run the following command to clone the Git repository to your local machine, using the following command:

git clone https://{name}.scm.azure-api.net/

Provide the username and password when prompted.

If you receive any errors, try modifying your git clone command to include the user name and password, as shown in the following example.

git clone https://username:password@{name}.scm.azure-api.net/

If this provides an error, try URL encoding the password portion of the command. One quick way to do this is to open Visual Studio, and issue the following command in the Immediate Window. To open the Immediate Window, open any solution or project in Visual Studio (or create a new empty console application), and choose Windows, Immediate from the Debug menu.

?System.Net.WebUtility.UrlEncode("password from the Azure portal")

Use the encoded password along with your user name and repository location to construct the git command.

git clone https://username:url encoded password@{name}.scm.azure-api.net/

After cloning completes, change the directory to your repo by running a command like the following.

cd {name}.scm.azure-api.net/

If you saved the configuration to a branch other than the default branch (master), check out the branch:

git checkout <branch_name>

Once the repository is cloned, you can view and work with it in your local file system. For more information, see File and folder structure reference of local Git repository.

Update your local repository with the most current service instance configuration

If you make changes to your API Management service instance in the Azure portal or using other Azure tools, you must save these changes to the repository before you can update your local repository with the latest changes.

To save changes using the Azure portal, select Save to repository on the Repository tab for your API Management instance.

Then, to update your local repository:

Ensure that you are in the folder for your local repository. If you've just completed the git clone command, then you must change the directory to your repo by running a command like the following.
```
cd {name}.scm.azure-api.net/
```
In the folder for your local repository, issue the following command.
```
git pull
```

Push changes from your local repo to the server repo

To push changes from your local repository to the server repository, you must commit your changes and then push them to the server repository. To commit your changes, open your Git command tool, switch to the directory of your local repository, and issue the following commands.

git add --all
git commit -m "Description of your changes"

To push all of the commits to the server, run the following command.

git push

Deploy service configuration changes to the API Management service instance

Once your local changes are committed and pushed to the server repository, you can deploy them to your API Management service instance.

Navigate to your API Management instance in the Azure portal.
In the left menu, under Deployment and infrastructure, select Repository > Deploy to API Management.
On the Deploy repository configuration page, enter the name of the branch containing the desired configuration changes, and optionally select Remove subscriptions of deleted products. Select Save.

For information on performing this operation using the REST API, see Tenant Configuration - Deploy.

File and folder structure reference of local Git repository

The files and folders in the local Git repository contain the configuration information about the service instance.
