Mistral AI Actions

AI is most useful when it sits inside the rest of your automation, not as a separate manual step. The Mistral AI integration lets your workflows call Mistral language models, generate embeddings for semantic search, and analyze images using your own Mistral API key, with the response available as a workflow variable for any later step.

Retrieving Your API Key

To get your API key, start logging in to “ console.mistral.ai ” with your usual credentials.

Open API Keys and click Create new key.

Give it a recognizable name, add any other relevant details, such as an Expiration time or Connector access scope, and lastly, click Create new key.

Copy the key and save it in an accessible place, as you'll need it for the connection.

How to Set Up Mistral AI

You can connect your Mistral AI in one of two ways:

Via the Workflow Builder

Create or edit a workflow in the Automation section.

Add an Action, switch to the Apps tab, then select any Mistral AI action.

Click Connect your account on the action card.

Via Settings

Go to the Integrations section inside your account settings. In there, locate Mistral AI in the integrations list and click Connect.

Paste your Mistral API key.

Click Save to complete the connection.

Available Actions

Once connected, you can start using the following Mistral AI actions:

Create Chat Completion

Send a prompt (and optional system prompt) to a Mistral language model and receive a generated text response.

Create Embeddings

Convert input text into a 1024-dimensional vector for semantic search, RAG, classification, or clustering.

Analyze Image (Vision)

Send an image URL and a prompt to a vision-capable Mistral model and receive a natural-language answer about the image.

Using these actions, you can easily implement multilingual customer reply generation and semantic FAQ matching for inbound questions, as well as extract receipts and documents from images, making your business more efficient and accessible across the board. We hope you enjoy it! 

FAQs

Q: Are Mistral AI actions premium workflow actions?
Yes. All three actions consume premium action credits at the standard automation rate, in addition to Mistral usage charges.
Q: Can I use workflow variables inside prompts?
Yes. Both the System Prompt and the Prompt accept inline variables, such as contact fields, custom fields, trigger payload values, and the outputs of earlier workflow steps.
Q: Where is the AI-generated response stored?
It is exposed as a workflow output variable on the action. Use it in messages, write it to custom fields, or pass it to downstream steps. It is not persisted as a separate record by default.
Q: What happens if Mistral returns an error or times out?
The action surfaces the error to the workflow execution log, and the workflow continues based on its configured branching. Always test the action before publishing, and add a fallback branch if reliability matters.
Q: Can the generated response be used in SMS or email messages?
Yes. The output variable can be inserted into Send SMS, Send Email, internal notifications, and any other messaging action.
