Hello Mautic Community,
I am currently facing one specific problem with my website’s Mautic form integration where a visitor can complete and submit a form successfully from the frontend, but the submission is occasionally not recorded by Mautic as expected. The form itself appears normally on the website, visitors can enter the required information, and after clicking the submit button they can receive the expected confirmation message, so from the visitor’s perspective the interaction appears to have completed successfully. However, when I check Mautic afterward, some of those submissions are missing even though the corresponding visitor reached the confirmation state on the website. This does not happen with every submission, and most form submissions are recorded normally, which makes the problem intermittent and difficult to reproduce. I am trying to troubleshoot this as one specific form-submission synchronization problem between my website and Mautic rather than several unrelated issues.
I have verified that the Mautic form is correctly configured and that the form fields displayed on the website correspond to the fields configured in Mautic. Normal submissions are appearing correctly in Mautic, including the expected contact information and submission data, so the integration is not completely broken. The problem seems to occur only with occasional requests where the frontend completes its submission flow but the corresponding record does not appear when I inspect Mautic. I have checked the website’s server logs and browser network requests to determine whether the form request is actually being sent and whether the browser receives a successful response. In affected cases, I am trying to compare the exact request sequence with a successful submission so I can establish whether the request reaches Mautic and is processed but not persisted, or whether the request fails somewhere before Mautic receives it.
I have started recording timestamps and non-sensitive submission identifiers so that I can compare the website’s logs with the Mautic logs around the same time. In successful cases, the form submission request is followed by the expected response and the contact or submission information becomes available in Mautic. In affected cases, the frontend can still show the normal confirmation message, but I cannot find the corresponding submission afterward. I have not found a consistent browser-side JavaScript error immediately before these missing submissions, and the website remains available throughout the process. I am therefore interested in understanding whether there is a recommended Mautic diagnostic method for determining whether a form request was received, queued, rejected, processed asynchronously, or otherwise failed before the submission became visible in the Mautic interface.
The issue appears more noticeable when several visitors submit the form within a relatively short period, although I have not been able to establish a precise threshold that reliably triggers it. Individual test submissions generally work, while occasional submissions can disappear when the website is handling more activity. I am checking the communication path between the website and Mautic, including request timing and response handling, because I want to make sure the frontend is not displaying a success state before the backend has actually confirmed that the submission has been processed. I am also reviewing whether any caching or proxy layer could interfere with the form request, although I do not want to disable caching across the entire website without evidence that it is involved. My main goal is to determine why the website and Mautic can disagree about whether a form submission was successfully recorded.
I have also tested the form directly and compared successful submissions with cases where the expected record is missing from Mautic. The website does not appear to experience a complete outage during these events, and other pages continue working normally. Because most submissions are processed correctly, I suspect that the problem may involve an intermittent request or processing condition rather than an invalid form configuration. I am currently reviewing the Mautic logs, application logs, and network responses to identify whether the affected submissions generate any warning or error that I may have overlooked. If Mautic provides specific logging, queue, API, form-processing, or contact-record diagnostics that can be used to trace a submission from the initial request through final storage, I would appreciate advice on which information is most useful to collect while reproducing the problem.
I would appreciate guidance from the Mautic community on how to systematically troubleshoot this specific situation where visitors can submit a Mautic form on my website and receive a successful confirmation message, but occasional submissions do not appear in Mautic afterward. In particular, I would like to know which Mautic logs, form-processing diagnostics, request details, queue information, or server-side checks would help determine whether the missing submission is reaching Mautic and where it stops being processed. I would also appreciate advice on how the website should handle the frontend confirmation state so that it only reports success when the submission has actually been accepted and processed correctly. My goal is to identify the underlying cause and make form submissions reliably appear in Mautic without requiring visitors to submit the form multiple times or creating duplicate contact records. Sorry for long post!
