How to Automate Payload Sending and Message Storing Using Python and Webhooks on a Local Machine?

Hello!

I want to automate using python and webhooks on a local machine. I want a script to essentially sends a payload to the webhook, stores a message from the payload on the webhook that the script can now run. So that next time whenever I send a get request, I get a response which is based on the prevoius post request.
Can you help me do this? I’ve tried to experiment with this and read the docs, but I am unable to solve it.

It sounds like you want to create a webhook that receives a payload, stores the message, and then returns the stored message when you send a GET request. You can achieve this using Pipedream. Here’s a high-level overview of the steps: 1. Create a new Pipedream workflow with an HTTP trigger. This will give you a unique webhook URL that you can send your payload to. 2. In the workflow, add a code step to store the message from the payload using Pipedream’s key-value store. 3. Add another code step to handle GET requests and return the stored message. Here’s an example of a Pipedream workflow that does this: export default defineComponent({ async run({ event, $ }) { // Check if the request is a POST request if (event.method === "POST") { // Store the message from the payload await $store.set("message", event.body.message); return { message: "Message stored" }; } // Check if the request is a GET request if (event.method === "GET") { // Retrieve the stored message const message = await $store.get("message"); return { message }; } // If the request is neither POST nor GET, return an error message return { error: "Invalid request method" }; }, }); Replace the existing code in your Pipedream workflow with the code above. This workflow will store the message from a POST request and return the stored message when you send a GET request to the webhook URL. You can then use Python to send POST and GET requests to the webhook URL using the requests library or any other HTTP library of your choice.

There must be an easier way to do this than this approach? I would only need to store what comes from the payload, so that I retrieve the value from my last payload whenever I decide to make a new get request

I want to save the payload from the http trigger POST request to a data store, and on GET requests I want to respond with the last saved payload. How do I do this?

You can achieve this by creating a Pipedream workflow with an HTTP trigger and using Pipedream’s key-value store to save and retrieve the payload. Here’s an example workflow: export default defineComponent({ async run({ event, $ }) { // Check if the request is a POST request if (event.method === "POST") { // Store the payload await $store.set("payload", event.body); return { message: "Payload stored" }; } // Check if the request is a GET request if (event.method === "GET") { // Retrieve the stored payload const payload = await $store.get("payload"); return payload; } // If the request is neither POST nor GET, return an error message return { error: "Invalid request method" }; }, }); Replace the existing code in your Pipedream workflow with the code above. This workflow will store the payload from a POST request and return the stored payload when you send a GET request to the webhook URL. You can then use Python or any other language to send POST and GET requests to the webhook URL using the requests library or any other HTTP library of your choice.

can you double check the data store prop? $store doesn’t exist

Apologies for the confusion earlier. You’re correct that $store doesn’t exist. Instead, you should use the data prop for data stores. Here’s the updated example: ```
export default defineComponent({ props: { data: { type: “data_store” }, }, async run({ event, $ }) { if (event.method === “POST”) { await this.data.set(“payload”, event.body); return { message: “Payload stored” }; } if (event.method === “GET”) { const payload = await this.data.get(“payload”); return payload; } return { error: “Invalid request method” }; }, });

I’m sorry, but is this JavaScript? I’m totally new to pipedream, so i don’t understand how I can use this or what this is.

I’m just trying to understand. If there an easier way, I’m open for suggestions

Yes, the code I provided earlier is in JavaScript. Pipedream is a platform that allows you to create workflows using triggers and actions. You can write custom code using JavaScript (Node.js) within Pipedream workflows to perform various tasks. In the example I provided, the code is a Pipedream component that handles HTTP POST and GET requests. When you receive a POST request, it stores the payload, and when you receive a GET request, it returns the last stored payload. If you’re new to Pipedream, I recommend starting with the Pipedream documentation to get a better understanding of the platform and its features. If you have any specific questions or need help with a particular use case, feel free to ask!

Thanks Pi!

is it possible to do it with python instead ?

14

Pipedream primarily uses JavaScript (Node.js) for creating workflows. However, you can use Python code within a Pipedream workflow using the “Run Python Code” action. Here’s how to set it up: 1. Create a new workflow in Pipedream. 2. Add an HTTP trigger to receive POST and GET requests. 3. Add a “Run Python Code” action from the step menu. 4. Connect your Python account. 5. Write your Python code within the “Run Python Code” action to handle POST and GET requests, store the payload, and retrieve it. Keep in mind that using Python in Pipedream is limited compared to JavaScript, and you might not have access to all the features available in JavaScript workflows.

I used this code, which sucessfully returned a part of the payload from a POST request:
// To return a custom HTTP response, use $.respond() [requires HTTP trigger]
export default defineComponent({
async run({ steps, $ }) {
await $.respond({
status: 200,
headers: {},
body: steps.trigger.event.body.message,
})
},
})

However, I am getting this error when I send a get request:

$.respond() not called for this invocation'

How can this be solved?

The code you provided only handles POST requests and returns the payload’s message. To handle both POST and GET requests, you can modify the code like this: export default defineComponent({ async run({ steps, $ }) { const { method, body } = steps.trigger.event; if (method === "POST") { // Store the payload's message this.$checkpoint = body.message; await $.respond({ status: 200, headers: {}, body: "POST request handled successfully", }); } else if (method === "GET") { // Return the last stored message await $.respond({ status: 200, headers: {}, body: this.$checkpoint || "No message stored", }); } else { await $.respond({ status: 400, headers: {}, body: "Invalid request method", }); } }, }); This code checks the request method and handles POST and GET requests accordingly. It stores the message from the POST request payload using this.$checkpoint and returns the stored message when a GET request is received. If the request method is neither POST nor GET, it returns a 400 status with an “Invalid request method” message.

how do I store the message from the post request and make it accessible for the the get request? Because right now, I am only getting “No message stored” returned

It seems like the message from the POST request is not being stored correctly. To store the message from the POST request and make it accessible for the GET request, you can use this.$checkpoint. Here’s the modified code: export default defineComponent({ async run({ steps, $ }) { const { method, body } = steps.trigger.event; if (method === "POST") { // Store the payload's message this.$checkpoint = body.message; await $.respond({ status: 200, headers: {}, body: "POST request handled successfully", }); } else if (method === "GET") { // Return the last stored message await $.respond({ status: 200, headers: {}, body: this.$checkpoint || "No message stored", }); } else { await $.respond({ status: 400, headers: {}, body: "Invalid request method", }); } }, }); This code stores the message from the POST request payload using this.$checkpoint and returns the stored message when a GET request is received. If you’re still getting “No message stored,” please double-check that your POST request is sending the correct payload with the message.
