Create and Run a Text-to-Image Workflow in Coze: Step-by-Step Guide

First, log into Coze (https://www.coze.cn/), go to Workspace / Resource Library, and create a new workflow named text2image (English only) with a description.

The workflow consists of a start node and an end node.

2.1 Add Image Generation Node

2.2 Connect Nodes

Link the start node to the image generation node and then to the end node.

2.3 Configure Image Generation Node

Model: portrait

Aspect ratio: 1:1

Input: add a variable and select “Start” as its value

Prompt: use {{variable_name}} to reference the variable

2.4 Configure End Node

Set the output to return the data field from the image generation node.

3 Test the Workflow

Run the workflow to verify it works. Adjust the input prompt (e.g., “a long‑haired woman in yoga pants standing next to a golf car”) until the generated image matches the description. If the output is empty, the generation failed and you should retry.

4 Publish the Workflow

After publishing, the workflow details page shows the workflow ID, for example workflow_id=7529898597627412506.

5 Coze API

5.1 Add Personal Access Token

Create a token by giving it a name, setting an expiration time, choosing the required permissions, and selecting the workspace. Copy the generated token (e.g.,

pat_b4hgp9Rn6iMYZUSmbTZih6YHdEkvNwZTm5SLja2aUIrdhL4jkIFvVvOKOGMmfZox

) because it cannot be retrieved later.

5.2 Run the API

Send a request containing the token, the workflow ID, and the required input parameters for the start node. The API returns a JSON object whose data field contains the image URL.

{
  "code":0,
  "cost":"0",
  "data":"{output":"https://s.coze.cn/t/WkLTawwU0H4/"}",
  "debug_url":"https://www.coze.cn/work_flow?execute_id=7529910616715886601&space_id=7529344229806686244&workflow_id=7529898597627412506&execute_mode=2",
  "msg":"Success",
  "token":0
}

Paste the output URL into a browser to view the generated image.
