The Scaleway API allows you to create and manage all your Scaleway resources programmatically. Anything you can do through the Scaleway console can also be done through the API.

Refer to the Scaleway Developers website for more information on the Scaleway API.

• A Scaleway account logged into the console
• Owner status or IAM permissions allowing you to perform actions in the intended Organization
• A valid API key
• Installed curl
• Made your first request using the Scaleway API

1. Run the following command in your terminal to create a functions namespace:

   curl -X POST \
   -H "X-Auth-Token: $SCW_SECRET_KEY" \
   -H "Content-Type: application/json" \
   -d '{
       "name": "<YOUR_NAMESPACE_NAME>",
       "project_id": "YOUR_PROJECT_ID"
   }' \
   "https://api.scaleway.com/functions/v1beta1/regions/fr-par/namespaces"

   An output similar to the following displays:

   {"id":"example-fb93-43e3-a036-7be69f1af7a1", "name":"your-namespace-name", "environment_variables":{}, "organization_id":"example-776f-4f65-a41e-6c5fc58b4076", "project_id":"example-c162-43f7-bb3e-1182e6f12342", "status":"pending", "registry_namespace_id":"", "error_message":null, "registry_endpoint":"", "description":"", "secret_environment_variables":[], "region":"fr-par"}%  

2. Run the following command to create a function:

   curl -X POST \
   -H "X-Auth-Token: $SCW_SECRET_KEY" \
   -H "Content-Type: application/json" \
   -d '{
     "name": "<YOUR_FUNCTION_NAME>",
     "namespace_id": "<YOUR_NAMESPACE_ID>",
     "runtime": "<RUNTIME>"
   }' \
   "https://api.scaleway.com/functions/v1beta1/regions/fr-par/functions"

   An output similar to the following displays:

   {"id":"ef777a64-1f4e-4d43-8227-26927c7de057", "name":"your-function-name", "namespace_id":"example-fb93-43e3-a036-7be69f1af7a1", "status":"created", "environment_variables":{}, "min_scale":0, "max_scale":5, "runtime":"python310", "memory_limit":256, "cpu_limit":140, "timeout":"300s", "handler":"handler.handle", "error_message":null, "privacy":"public", "description":"", "domain_name":"namespaceg04rnwx-function-example.functions.fnc.fr-par.scw.cloud", "secret_environment_variables":[], "http_option":"enabled", "runtime_message":"", "build_message":null, "region":"fr-par"}%  

3. Create a zip file containing your function's code by following this procedure.

   For testing purposes, you can create a zip archive with a simple Python file named `handler.py` at the root of the archive, that contains the following code:

   def handle(event, context):
   return {
       "body": {
           "message": 'Hello, world',
       },
       "statusCode": 200,
   }

4. Upload your zip file using the Scaleway console or the Scaleway API.

5. Run the following command to deploy your function:

   curl -X POST \
     -H "X-Auth-Token: $SCW_SECRET_KEY" \
     -H "Content-Type: application/json" \
     -d '{}' \
     "https://api.scaleway.com/functions/v1beta1/regions/fr-par/functions/<YOUR_FUNCTION_ID>/deploy"

   Your function is now being deployed.

   You can check the status of your function from the [Scaleway console](https://www.console/scaleway.com/) or by running the following command:

   curl -X GET \
     -H "X-Auth-Token: $SCW_SECRET_KEY" \
     "https://api.scaleway.com/functions/v1beta1/regions/fr-par/functions/<YOUR_FUNCTION_ID>"

6. Run the following command to call your function once it is deployed:

   curl <YOUR_FUNCTION_ENDPOINT>
