## Error Meaning
Bad request - please check your parameters
This error message occurs when the name or format of the data sent from n8n differs from the data expected by the Gamma API.
The error details' "inputText must be a string" is the biggest clue. This indicates that the Gamma API is expecting a parameter named inputText .
In the previous configuration, we sent two parameters, title and content , but the current API specification requires that they be sent as a single parameter named inputText .
## Fix
Change the HTTP Request node settings as follows.
Proceed to the Body Parameters settings.
Delete the existing parameters title and content .
Add a single new parameter and configure it as follows:
Name: inputText
Value: Enter all Markdown content, including the title line, here.
Example of Value:
Combine the data previously separated into title and content into a single text string, as shown below.
