How to detect and fix errors in HTTP requests from your bot
🧠 Introduction
HTTP requests allow you to connect your bot to external services such as CRMs, internal systems, or platforms like Zapier. However, a bad configuration can cause this data to never reach the destination... and without warning!
This article will help you identify and resolve the most common errors when using this component.
🧨 Frequent errors when using the HTTP component
| Error |
| What happens |
| How to prevent it |
| Double inclusion of URLs |
| The address is concatenated twice, like: https://hooks.zapier.../...
| Check that the URL does not have duplicates when copying/pasting. It should always start with https:// and not contain another https:// inside |
| Invalid or badly copied URL |
| The flow doesn't send anything, not even an error |
| Paste the URL into the browser to validate the format or use tools like Postman |
| HTTP component is not activated |
| The user does not reach that part of the flow due to unfulfilled conditions |
| Review the flow design and simulate a conversation to ensure it is activated |
| Silent error in Zapier |
| Zapier does not register the entry, but does not throw a visible error either |
| Check if the webhook is configured correctly. In Zapier, check the last requests received in the task history |
🧪 Example: What to do if the information did not reach Zapier
📤Review the URL of the HTTP request in AtomVerify that it only has one valid address. Avoid accidental concatenations.

🛠 Recommendations for testing your requests
Use Postman or similar tools to validate that the endpoint responds correctly.
Manually test the body of the request with real data.
If you use dynamic variables (,), make sure that those variables are populated before activating the request.
Add a "validation message" step before and after the HTTP to track if it was executed.
✅ Good practices for this scenario
Don't paste URLs from editors that may include invisible characters.
Test each change with test users or in a copy of the flow.
Document internally what the valid URL is and who administers it (useful if you use multiple webhooks).
🔎 System fields that are not sent correctly: how to detect it
Sometimes, even if the HTTP component runs correctly, external systems like Zapier or your CRM do not receive some key values such as phone number, name, or email. This may be due to a silent failure in capturing system fields.
🧪 How to identify if the field was not sent?
Review the conversation logsFrom the conversation history, verify if the HTTP request step was executed. If the field appears empty (nullo""), it means that it was not previously captured or was overwritten.

Confirm that the data was saved correctlyIf you use components such as "Save field", validate that the value is populated before the integration step. For system fields such as phone, avoid overwriting them with other values in the flow.

⚠️ Errors due to discrepancy in data types in HTTP requests
In some cases, the bot may receive a data type from the API that is different from what is expected in the flow, which may cause:
The value is not stored correctly
The value is not stored correctly
A silent error is triggered during execution
A silent error is triggered during execution
The flow does not continue as expected
The flow does not continue as expected
🎯 Common scenario: Boolean vs. String
A common situation is that the service returns a boolean (true/false) value but the flow field is prepared to store a text string.
Typical error:
This can happen, for example, when trying to directly save the API response in a user field without prior validation or transformation.
🛠️ How to prevent it?
You can use the Manage errors option within the HTTP Request component, which allows you to:
Verify if the API returns a different type than expected.

Apply a condition to transform the value before saving it.

Redirect to another part of the flow in case of error.

📌 Practical example
Suppose the endpoint returns:
But the destination field in Atom expects text. In this case, you could:
Create a "Save field" component with a condition: IfcanPayistrue, save"Yes" IfcanPayisfalse, save"No"
Create a "Save field" component with a condition:
IfcanPayistrue, save"Yes"
IfcanPayistrue, save"Yes"
IfcanPayisfalse, save"No"
IfcanPayisfalse, save"No"
Or directly transform the data in the API logic, if possible.

🧪 Recommendations before testing
| Step |
| Action |
| ✅ |
| Test in Postman with the exact values |
| 🔄 |
| Compare the result with what the flow expects |
| 🧰 |
| Use "Manage errors" in the HTTP Request component |
| 💬 |
| Simulate the complete conversation from Atom |
💡 Additional tip
If your flow expects text-type values, make sure that all the responses you expect to save are as strings (in quotes) or mapped correctly before being processed by the bot.
