Make.com error toasts
'Webhook test failed. Check your URL and settings.' - the URL is wrong, unreachable, or the Make scenario is turned off. Turn the scenario on in Make, confirm the URL is correct, and try Test Webhook again.
No response from the endpoint - your backend or service is down or timing out. Check the endpoint directly.
Leadbyte error toasts
Leadbyte errors appear as 'LeadByte Error: {message}' toasts. If the API returns multiple errors, each appears as a separate toast.
If the Test Leadbyte button is greyed out, check that all three credentials are saved: Campaign ID, API URL, and API Key. The button only activates when all three are present.
Invalid API key - double-check the key matches the Leadbyte account for the campaign.
Missing required fields - the campaign requires fields your mapping has not filled in. Expand Field Mapping, add the missing row, save, and test again.
Wrong Campaign ID - confirm the ID matches the campaign you want to post into.
Tracking issues
If GTM tags are not firing on every step, the most common cause is using a Page View trigger instead of a History Change trigger. Multi-step forms navigate without a full page reload. In GTM, go to Triggers > New > History Change > All History Changes, and apply that trigger to your tags.
