Prerequisites
Before creating a Mistral AI credential, you need to obtain your API key, model name, and base URL from your Mistral AI account. Mistral AI uses API key authentication for all API requests, with the API key sent in the Authorization header with the Bearer prefix.
To obtain your Mistral AI API credentials, follow these steps:
-
Sign in to your Mistral AI account using your administrator credentials, or create a new account at Mistral AI.
-
Navigate to your account dashboard or settings section.
-
Look for the API Keys or API section in your account settings.
-
If you don't have an API key yet, click Generate API Key or Create API Key to create a new API key.
-
Copy the API key immediately after it's generated, as it may not be accessible again after you navigate away from the page.
-
Identify the model name you want to use (e.g.,
mistral-small-latest,mistral-medium-latest,mistral-large-latest). Model names are available in the Mistral AI documentation and may vary based on your account type and available models. -
Identify the base URL for the LLM API endpoint. The base URL is typically
https://api.mistral.ai/v1/chat/completionsfor chat completion endpoints, but may vary based on your specific use case and endpoint requirements. -
Store all credentials securely, as you will need them to configure your Nexla credential. The API key is sensitive information and should be kept confidential.
The API key is sent in the Authorization header with the Bearer prefix (e.g., Authorization: Bearer {api_key}) for all API requests to the Mistral AI API. The model name determines which Mistral AI model will be used for processing requests. The base URL specifies the endpoint for LLM API calls. The API key authenticates your requests and grants access to Mistral AI resources based on your account permissions. If your API key is compromised, you should immediately revoke it in your Mistral AI account settings and generate a new one. For detailed information about obtaining API keys, API authentication, available models, and API endpoints, refer to the Mistral AI API documentation.
Authenticate
Credentials required
| Field | Required | Secret | Description |
|---|---|---|---|
| API Key Value | Yes | Yes | Your API KEY for this model |
| Model Name | Yes | No | The name of the model you want to use (Ex.: mistral-small-latest). |
| Base Url for the LLM Call | Yes | No | Provide the full endpoint to the LLM call on Mistral ex : https://api.mistral.ai/v1/chat/completions |
Create a credential in Nexla
- After selecting the data source/destination type, click the Add Credential tile to open the Add New Credential overlay.
New Credential Overlay – Mistral AI

-
Enter a name for the credential in the Credential Name field and a short, meaningful description in the Credential Description field.
-
Mistral AI uses API key authentication for all API requests. The API key is sent in the
Authorizationheader with theBearerprefix to authenticate API requests to the Mistral AI API. Enter your Mistral AI API key in the API Key Value field. This is the API key you obtained from your Mistral AI account settings (API Keys section). The API key is sensitive information and must be kept confidential. -
Enter the model name in the Model Name field. This should be the name of the Mistral AI model you want to use (e.g.,
mistral-small-latest,mistral-medium-latest,mistral-large-latest). The model name determines which Mistral AI model will be used for processing requests. Model names are available in the Mistral AI documentation and may vary based on your account type and available models. -
Enter the base URL for the LLM API endpoint in the Base Url for the LLM Call field. This should be the complete endpoint URL for the LLM API call on Mistral AI (e.g.,
https://api.mistral.ai/v1/chat/completions). The base URL specifies the endpoint for LLM API calls and may vary based on your specific use case and endpoint requirements.Your Mistral AI API key can be found in your Mistral AI account settings under the API Keys section. The API key is sent in the
Authorization: Bearer {api_key}header for all API requests to the Mistral AI API. The model name determines which Mistral AI model will be used for processing requests, and the base URL specifies the endpoint for LLM API calls.If your API key is compromised, you should immediately revoke it in your Mistral AI account settings and generate a new one. The API key provides access to your Mistral AI account and should be treated as sensitive information. Keep your API key secure and do not share it publicly.
For detailed information about obtaining API keys, API authentication, available models, and API endpoints, see the Mistral AI API documentation.

Click the Save button at the bottom of the overlay. The newly added credential will now appear in a tile on the Authenticate screen during data source/destination creation.
Use as a data source
To create a new data flow, navigate to the Integrate section, and click the New Data Flow button. Select the Mistral AI connector tile, then select the credential that will be used to connect to your Mistral AI account, and click Next; or, create a new Mistral AI credential for use in this flow.
Endpoint templates
Nexla provides pre-built templates that can be used to rapidly configure data sources to interact with common Mistral AI endpoints. Select the endpoint from which this source will fetch data from the Endpoint pulldown menu. Available endpoint templates are listed in the expandable boxes below.
Once the selected endpoint template has been configured, click the Test button to the right of the endpoint selection menu to retrieve a sample of the data that will be fetched. Sample data will be displayed in the Endpoint Test Result panel on the right, allowing you to verify that the source is configured correctly before saving.
Manual configuration
Mistral AI data sources can also be manually configured to interact with any valid Mistral AI API endpoint, including endpoints not covered by the pre-built templates, chained API calls, or custom request parameters. Select the Advanced tab at the top of the configuration screen, and follow the instructions in Connect to Any API to configure the API method, endpoint URL, date/time and lookup macros, path to data, metadata, and request headers.
The Mistral AI API typically uses the POST method for chat completion and other LLM operations. The request body must be valid JSON matching the Mistral AI API's expected format — for chat completion endpoints, this is a messages array containing objects with role and content properties, e.g. {"messages":[{"role":"user","content":"{your_message}"}]}. For the Response Data Path, use a JSONPath expression such as $ to extract the entire response object, or $.choices[*] to extract all choices from a chat completion response.
Once all of the relevant settings have been configured, click the Next button to proceed with the rest of the data flow configuration, or click Save to save the new Mistral AI data source.
