Access
How do I get API access and authentication credentials?
Are your APIs free to use?
Yes. Our API solutions are available for use at no cost. There are no usage fees or subscription costs for access to our API endpoints.
Do I need an existing customer account to use the API?
No. You do not need an existing customer account to access product information. However, you will need a customer account to access location-specific lead time, inventory and pricing details.
Functionality and Features
What product information is available through the API?
Molex’s suite of API endpoints provides access to a rich collection of product information including general catalog details, detailed part attributes, technical drawings, CAD models, product images, packaging details, compliance details, lifecycle statutes, inventory levels and pricing.
Can I access my account-specific pricing through the API?
Yes. Our pricing API endpoint uses your sold-to customer account number to return account-specific pricing including regional book and contract pricing details.
Can I place orders through your API?
No. We are unable to accept orders through our API at this time.
What is the difference between API and EDI integration?
EDI is typically used for structured, batch-based transactional exchanges between systems. APIs provide real-time, on-demand integration, enabling systems to dynamically retrieve and exchange data.
Authentication
What authentication methods are supported?
Molex API solutions implement the OAuth 2.0 authorization framework, an industry-standard providing secure, delegated access to protected resources. Each request to an API endpoint will require a valid access token.
How sensitive is my Client ID and Client Secret?
Each connected application is assigned a unique Client ID and Client Secret with access to our API endpoints. It is important to keep your Client ID and Client Secret private and secured at all times. To protect our shared interests, your authentication details must never be made public.
What is the process for handling errors?
Our API endpoints return standard HTTP status codes, along with detailed error messages for quick troubleshooting. Errors with status codes in the 5xx range (for example, 500) indicate an issue with our system. If you encounter persistent errors with status codes in that range, please contact our support team for assistance.
Structure and Performance
What is the API rate limit?
Clients in our production environment may make up to 400 API calls per minute. As interactive features are added, we may apply different limits to individual endpoints. Please contact our support team if a higher volume of calls is required.
How current is the data returned?
For most endpoints, the information is updated within 24 hours. In critical use cases, more recent data can be made available. Inventory levels are updated every 30 minutes.
Troubleshooting
What is the process for handling errors?
Our API endpoints return standard HTTP status codes, along with detailed error messages for quick troubleshooting. Errors with status codes in the 5xx range (for example, 500) indicate an issue with our system.
