Ignition primarily supports HTTP-based APIs, which allows for RESTful API calls. It can also work with SOAP APIs through third-party libraries. There is no explicit mention of native support for newer API types like GraphQL or gRPC in the provided search results.
The choice of API type to use with Ignition would typically depend on the requirements of the specific project and the APIs supported by the systems Ignition needs to interact with.
Based on the search results provided, it does not appear that the official Ignition API has built-in webhook functionality. However, there are some key points to consider:
While Ignition does not have native webhook support, it is possible to implement webhook-like functionality using scripts and HTTP requests.
Developers have created custom solutions to send data from Ignition to external services using webhooks:
One approach is to use Gateway Tag Change Scripts to trigger HTTP POST requests when tag values change.
Another method involves using notification pipelines and script blocks to send alarm event notifications to services like Slack via webhooks.
The implementation typically involves:
While not native webhooks, these custom implementations allow you to send data from Ignition to external services based on events like:
The exact events you can "subscribe" to depend on how you implement the custom webhook-like functionality. Common use cases include:
It's worth noting that while these custom solutions can achieve webhook-like behavior, they are not the same as a built-in webhook API that external services could subscribe to directly.
In summary, while Ignition does not have official webhook support in its API, developers have found ways to implement similar functionality using scripts and HTTP requests. The events you can react to depend on how you structure your custom implementation.
Based on the search results provided, I could not find any specific information about the API rate limits for the Ignition API. The search results mainly contain general information about Ignition's platform, modules, and documentation, but do not mention any rate limiting details for their API.
However, I can provide some general information about API rate limits and best practices:
API rate limits are typically implemented to ensure fair usage and prevent abuse of the API.
Rate limits can be based on various factors such as:
Different endpoints within an API may have different rate limits.
Rate limits are often tied to API keys or user accounts.
Check the official Ignition API documentation for specific rate limit information.
Contact Ignition's support or sales team if you need clarification on their API rate limits.
Implement proper error handling in your code to deal with potential rate limit errors.
Consider implementing a backoff strategy if you encounter rate limit errors.
If you require higher rate limits for your application, reach out to Ignition to discuss your needs.
While not specific to Ignition, here are some general practices for handling API rate limits:
Look for rate limit information in API responses. Many APIs include headers like:
X-RateLimit-Limit: 1000
X-RateLimit-Remaining: 998
If you encounter a rate limit error, it's typically returned with an HTTP status code of 429 (Too Many Requests).
Implement proper error handling to catch and respond to rate limit errors in your application.
Since the search results don't provide specific information about Ignition API rate limits, I recommend contacting Ignition directly or consulting their official API documentation for accurate and up-to-date information on their rate limiting policies.
Based on the search results provided, I can answer your question about the most recent version of the Ignition API:
The most recent version of the Ignition API package is 8.1.42, released on June 24, 2024 [3].
Key points to consider:
This version is available as a Python package that can be installed using pip [3].
It requires Python 2.7.18 [3].
The package allows developers to get code completion for Ignition Scripting API functions in their IDE of choice [3].
It can be installed using the command: python2 -m pip install ignition-api [3].
While this is the most recent version of the API package, it's important to note that Ignition itself may have more recent versions. The search results don't provide information about the latest Ignition platform version, only about the API package.
Best practices:
Always check the official Inductive Automation website for the most up-to-date information on Ignition versions and compatibility.
When using the API package, ensure your Python environment is compatible (Python 2.7.18).
Keep your Ignition installation and API package updated to benefit from the latest features and bug fixes.
