Managing Lambda Functions

After creating a lambda, use the management API to inspect it, update its supported fields, list all lambdas in the account, or delete it.

Function Structure

JavaScript lambdas export a default handler. The handler receives a request object and returns the response body you want HolaCloud to send back.

 1export default (req) => {
 2  return {
 3    body: {
 4      method: req.method,
 5      path: req.path,
 6      headers: req.headers,
 7      data: req.body
 8    }
 9  };
10};

Static lambdas use one of the static language modes: static-html, static-css, or static-js. In those modes, code is the content served for the matching lambda.

Updating a Lambda

Use PATCH /api/v0/lambdas/{lambda_id} to update name, language, code, method, or path.

1curl -X PATCH "https://api.hola.cloud/api/v0/lambdas/YOUR_LAMBDA_ID" \
2  -H "X-Glue-Authentication: YOUR_TOKEN" \
3  -H "Content-Type: application/json" \
4  -d '{
5    "name": "hello-updated",
6    "method": "POST",
7    "path": "/hello-updated",
8    "code": "export default (req) => ({ body: { message: \"Updated lambda\", data: req.body } })"
9  }'

Expected response:

 1{
 2  "id": "f3b2c1a0-1234-5678-9abc-def012345678",
 3  "created_timestamp": 1750507200,
 4  "owner": "user_123",
 5  "project_id": "project_456",
 6  "name": "hello-updated",
 7  "language": "javascript",
 8  "code": "export default (req) => ({ body: { message: \"Updated lambda\", data: req.body } })",
 9  "method": "POST",
10  "path": "/hello-updated"
11}

Viewing Lambda Details

Retrieve one lambda by ID:

1curl "https://api.hola.cloud/api/v0/lambdas/YOUR_LAMBDA_ID" \
2  -H "X-Glue-Authentication: YOUR_TOKEN"

Listing All Lambdas

1curl "https://api.hola.cloud/api/v0/lambdas" \
2  -H "X-Glue-Authentication: YOUR_TOKEN"

Deleting a Lambda

Permanently remove a lambda:

1curl -X DELETE "https://api.hola.cloud/api/v0/lambdas/YOUR_LAMBDA_ID" \
2  -H "X-Glue-Authentication: YOUR_TOKEN"

A successful deletion returns the API response for the deleted lambda or a confirmation payload, depending on the deployed API version.
