To use Hugging Face integration in n8n, start by adding the HTTP Request node to your workflow canvas and authenticate it using a generic authentication method. Once connected, you can make custom API calls to Hugging Face to query the data you need using the URLs you provide, for example: after setting up the HTTP Request node, you can use it to retrieve text generation results from Hugging Face’s models by making a POST request to the model's endpoint with the appropriate payload. For example, you can generate text by sending a prompt to a language model, or classify text by making a request to a sentiment analysis model. Additionally, you can automate workflows by integrating model responses into further processing steps, such as storing results in a database or triggering notifications based on outcomes.
