Ever wondered how you can take your workflow to the next level? Well, buckle up because we’re about to dive into the world of custom executions data with n8n. If you’re like me, always looking for ways to streamline processes and make data work harder for you, then you’re in for a treat. Let’s talk about how you can use the Code node to supercharge your workflows, filter your data like a pro, and make your life a whole lot easier.
What is Custom Executions Data and Why Should You Care?
Custom executions data is your secret weapon in n8n. It’s available on various platforms like Cloud: Pro, Enterprise, and Self-Hosted: Enterprise, registered Community, and you can start using it from version 0.222.0 and above. So, why should you care? Because it lets you add custom data to your workflow executions, which you can then use to filter and access your data more efficiently. Think about it: you’re not just managing your workflow; you’re optimizing it to work smarter, not harder.
How to Set Custom Data with the Code Node
Setting custom data is as easy as pie. You can do it using the Code node or directly within n8n, and it gets recorded with each execution. Here’s how you can set a single piece of extra data:
- JavaScript:
$execution.customData.set('key', 'value'); - Python:
_execution.customData.set('key', 'value');
Want to set all your extra data at once? No problem. Just use this:
- JavaScript:
$execution.customData.setAll({'key1': 'value1', 'key2': 'value2'}); - Python:
_execution.customData.setAll({'key1': 'value1', 'key2': 'value2'});
Now, let’s talk about the nitty-gritty. There are some limitations you need to keep in mind:
- Custom data must be strings.
- The key has a maximum length of 50 characters.
- The value has a maximum length of 255 characters.
- n8n supports a maximum of 10 items of custom data.
But don’t let these limitations hold you back. They’re just guardrails to keep things running smoothly.
Accessing Your Custom Data
So, you’ve set your custom data, but how do you access it? During the execution, you can check the current state of the object like this:
- JavaScript:
const customData = $execution.customData.getAll(); - Python:
customData = _execution.customData.getAll();
Or, if you want to access a specific value set during this execution, just use:
- JavaScript:
const customData = $execution.customData.get('key'); - Python:
customData = _execution.customData.get('key');
But here’s something important to note: you can’t retrieve custom data using the Execution Data node. So, make sure you’re using the Code node to fetch your data.
Filtering Your Executions List
Now, let’s get to the fun part: filtering your executions list. With custom executions data, you can filter your list based on the data you’ve set. This means you can quickly find the executions that matter most to you, saving you time and effort. It’s like having a superpower for your workflow management.
Real-World Applications
I’ve used custom executions data in my own workflows, and let me tell you, it’s a game-changer. For example, if you’re running a marketing campaign, you can set custom data to track different aspects of your campaign, like the source of leads or the type of content. Then, you can filter your executions list to see which campaigns are performing best. It’s all about making data-driven decisions that drive results.
Enhance Your Workflow with n8n
So, are you ready to enhance your workflow with n8n? With custom executions data, you have the tools to take your workflow to the next level. It’s not just about managing your data; it’s about using it to make smarter, faster decisions. And let’s be real, who doesn’t want that?
