Hailuo Videos Generation API Integration Instructions

This article will introduce the integration instructions for the Hailuo Videos Generation API, which can generate official Hailuo videos by inputting custom parameters.

Application Process

To use Hailuo Videos Generation API, first open the Ace Data Cloud Console and copy your API Token.

If you are not logged in, you will be redirected to sign in and brought back to this page automatically.

A single API Token works across every service on the platform — no need to subscribe per service. New accounts receive free starter credit; when it runs low you can top up your shared balance in the console.

Basic Usage

First, understand the basic usage method, which involves inputting the prompt prompt, the action action, the first frame reference image first_image_url, and the model model to obtain the processed result. You first need to simply pass a field action with the value generate, and then we also need to input the model. Currently, there are mainly two models: the image-to-video model minimax-i2v and the text-to-video model minimax-t2v. The specific content is as follows:

Here we can see that we have set the Request Headers, including:

  • accept: the format of the response result you want to receive, filled in as application/json, which means JSON format.
  • authorization: the key to call the API, which can be directly selected after application.

Additionally, we set the Request Body, including:

  • model: the model for generating the video, mainly the image-to-video model minimax-i2v and the text-to-video model minimax-t2v.
  • action: the action for this video generation task.
  • first_image_url: the link to the first frame reference image that must be uploaded when selecting the image-to-video model minimax-i2v, Base64 encoding is not supported.
  • prompt: the prompt.
  • callback_url: the URL to receive the callback result.

After selection, you can find that the corresponding code is also generated on the right side, as shown in the image:

Click the "Try" button to test, as shown in the above image, we obtained the following result:

{
  "success": true,
  "task_id": "baf1034c-684c-46be-ae6d-89ebb89b690d",
  "trace_id": "3221eb74-1a25-447a-ba69-7d9b310e306c",
  "data": [
    {
      "id": "0pv8yhe4fdrge0cmckpv23pd2g",
      "model": "minimax-t2v",
      "prompt": "Internal heat",
      "video_url": "https://file.aigpai.com/czjl/qoueLWBokF3ud6tdVD6VJTZuXTnK5HaMO2qAOS46Ef8VSBFUA/tmp9e3u11c1.output.mp4",
      "state": "succeeded"
    }
  ]
}

The returned result contains multiple fields, described as follows:

  • success: the status of the video generation task at this time.
  • task_id: the ID of the video generation task at this time.
  • trace_id: the tracking ID of the video generation at this time.
  • data: the result list of the video generation task at this time.
    • id: the video ID of the video generation task at this time.
    • prompt: the prompt of the video generation task at this time.
    • model: the cover link of the video generation task at this time.
    • video_url: the video link of the video generation task at this time.
    • state: the status of the video generation task at this time.

We can see that we have obtained satisfactory video information, and we only need to obtain the generated Hailuo video based on the video link address in the data result.

Additionally, if you want to generate the corresponding integration code, you can directly copy the generated code, for example, the CURL code is as follows:

curl -X POST 'https://api.acedata.cloud/hailuo/videos' \
-H 'accept: application/json' \
-H 'authorization: Bearer {token}' \
-H 'content-type: application/json' \
-d '{
  "action": "generate",
  "prompt": "Internal heat"
}'

Asynchronous Callback

Since the time taken by the Hailuo Videos Generation API to generate is relatively long, approximately 1-2 minutes, if the API does not respond for a long time, the HTTP request will keep the connection open, leading to additional system resource consumption. Therefore, this API also provides support for asynchronous callbacks.

The overall process is: when the client initiates a request, an additional callback_url field is specified. After the client initiates the API request, the API will immediately return a result containing a task_id field information, representing the current task ID. When the task is completed, the result of the generated video will be sent to the client-specified callback_url in the form of a POST JSON, which also includes the task_id field, allowing the task result to be associated by ID.

Let’s understand how to operate specifically through an example.

First, the Webhook callback is a service that can receive HTTP requests, and developers should replace it with the URL of their own HTTP server. For convenience in demonstration, we use a public Webhook sample site https://webhook.site/, where you can open the site to get a Webhook URL, as shown in the image:

Copy this URL, and it can be used as a Webhook. The sample here is https://webhook.site/580b81f5-596e-4321-b03f-606770b0bb83.

Next, we can set the field callback_url to the above Webhook URL, while filling in the corresponding parameters, as shown in the image:

Click to run, and you will immediately receive a result, as follows:

{
  "task_id": "05aff65c-5e84-442b-8e29-3a5d27130840"
}

After a moment, we can observe the generated video result at https://webhook.site/580b81f5-596e-4321-b03f-606770b0bb83, as shown in the image:

The content is as follows:

{
    "success": true,
    "task_id": "05aff65c-5e84-442b-8e29-3a5d27130840",
    "trace_id": "b9856b8a-725d-45c9-befe-e789d9fd9ffb",
    "data": [
        {
            "id": "t80jhsf96srg80cmcm6b0rk8gm",
            "model": "minimax-t2v",
            "prompt": "Internal heat",
            "video_url": "https://file.aigpai.com/czjl/YPaUz2DcwpJqItTXAG9XHAoEoj3dbF0XPU69LT5nefCMzBFUA/tmp8s_59jez.output.mp4",
            "state": "succeeded"
        }
    ]
}

We can see that the result contains a task_id field, and the other fields are similar to the previous text, allowing the task to be associated through this field.

Error Handling

When calling the API, if an error occurs, the API will return the corresponding error code and message. For example:

  • 400 token_mismatched: Bad request, possibly due to missing or invalid parameters.
  • 400 api_not_implemented: Bad request, possibly due to missing or invalid parameters.
  • 401 invalid_token: Unauthorized, invalid or missing authorization token.
  • 429 too_many_requests: Too many requests, you have exceeded the rate limit.
  • 500 api_error: Internal server error, something went wrong on the server.

Error Response Example

{
  "success": false,
  "error": {
    "code": "api_error",
    "message": "fetch failed"
  },
  "trace_id": "2cf86e86-22a4-46e1-ac2f-032c0f2a4e89"
}
