I have a custom integration that keeps Total Synergy and Trello in sync through their public REST APIs. Lately, I’ve spotted dates drifting out of alignment, so the immediate objective is to pinpoint where the sync is breaking down – I’m not chasing speed improvements yet, just accuracy. Your task will involve: - Checking that the webhooks are functioning properly based on the required functionality. - Analyzing and ensuring accurate database syncing between Total Synergy and Trello. - Debugging any issues you uncover with explanations provided. This is a one-time fix. However, if your work is excellent and meets expectations, there is an opportunity for another job within the same system involving changes and further debugging. Deliverables: • Ensure all noted discrepancies are resolved as per the requirements explained above. • Note any additional inaccuracies or other incorrect data uncovered during the process for future reference. I’ll supply access to Total Synergy, Trello, and the integration database for seamless work.

Hi there, I will trace the date drift in your Total Synergy to Trello sync by auditing each API call, webhook payload, and datatable mapping for start, due, and modified fields. Any other field mismatches I find along the way get documented too. A common culprit: timezone or UTC offset mishandling between the two APIs. I will verify that first. Questions: 1) Are the drifting dates consistently off by a fixed offset, or random? 2) Is the sync bidirectional, or does one system act as the source of truth? Send me a message and we can go over the details. Best regards, Kamran

Hi, I reviewed your Synergy Trello API sync audit and understand the goal: pinpoint where RESTful API date fields (start, due, modified) drift out of alignment, then fix the wrong data being pushed or pulled. I’ll trace the existing API Development flow end-to-end, auditing API calls, RESTful API request/response handling, datatable mappings for date management, and webhook logic that updates records. I’ll compare what the integration reads from Trello versus Total Synergy, then correct mapping rules so date values stay consistent. With careful software testing and clean, documented fixes, you’ll get accurate synchronization. Let’s discuss here now.

Hi, I can see the real pain here: the sync isn’t failing loudly, it’s quietly shifting dates and eroding trust in the data. I’ve worked on API-based integrations, webhook flows, and database-backed sync logic in PHP/MySQL, so I’m confident I can trace where Total Synergy and Trello are drifting apart. I’ll inspect the REST calls, datatable mappings, webhook handling, and the integration database to isolate every point where start, due, or modified dates may be transformed incorrectly, then fix the root cause and note any related field mismatches I uncover. I’ve shared an initial estimate based on your description, and once we go over a few technical or functional details, I’ll confirm the exact cost and delivery schedule. If you have any known example records where the dates diverged, I can use those as a fast reference point. I’ll also check whether timezone handling, field normalization, or update loops are contributing to the drift. Would you like me to prioritize the earliest known broken sync record so I can trace the exact date drift path first? Thanks, Asad

Hello sir, It seems you want me to locate why dates and other fields are drifting between Total Synergy and Trello and fix the sync so records match accurately. I'll start by validating webhook delivery and handlers, then trace the sync flow from incoming webhook to database write to Trello API calls, checking for timezone/conversion bugs, retry logic, race conditions, and missed or duplicate updates. I’ll use the integration logs, API request/response captures, and direct DB queries to reproduce mismatches and provide annotated fixes and brief explanations for each issue found. Can you share more details about the project, such as: 1. Which language/runtime the integration runs on and the database type (Postgres, MySQL, etc.)? 2. Where I can access webhook delivery logs, API request logs, and example mismatched records? 3. Any known timezones, daylight-saving adjustments, or batching/retry behavior implemented? Based on the last points, we can decide the scope, timeframe, and budget. I would be happy to discuss your project further. I look forward to hearing from you. Thank you!

Start by tracing one affected card/project all the way through both APIs before changing code. If the dates are drifting, I'd want to see the raw Synergy payload, raw Trello payload, stored mapping/datatable row, webhook event order, and the update direction that last touched start, due, and modified. I'd treat this as an integration correctness audit first, then patch the smallest faulty branch. Date-only fields, timezone coercion, UTC/local conversions, Trello due reminders, and "modified" timestamps used as sync triggers can all look correct in isolation but still push bad values once webhooks replay or arrive out of order. I'd also note any adjacent bad mappings I find, but keep the actual fix focused on the discrepant fields. M1: Trace the current bad case through API calls, stored mappings, webhook logs, and date transforms, $182 AUD, 1 day. M2: Patch the faulty transform/sync branch for start, due, and modified dates, $184 AUD, 1 day. M3: Regression test both sync directions, document the findings, and flag any other incorrect data fields, $184 AUD, 1 day. $550 AUD is my starting number from the brief. If the unknown here is mainly missing webhook history or a larger datatable mapping layer than described, I'll tighten the scope once I see the repo and one real discrepant record. Do you already have logs for the problem case, and is Synergy meant to be the source of truth for all three date fields?

. Since the integration is already working, I'll focus on identifying the exact source of the date mismatch rather than applying temporary fixes. My Approach: • Audit REST API requests/responses, webhook events, and database field mappings for start, due, and modified dates. • Trace data flow end-to-end, identify discrepancies, and implement a permanent fix with validation testing. • Document the root cause and any additional mapping issues discovered during the audit. Are the date discrepancies occurring in one direction only (Synergy → Trello or Trello → Synergy), or both? Please ping me to get started and deliver outstanding results Thanks!!!

The priority here is accuracy in the existing Total Synergy–Trello REST API sync, especially the drifting start, due, and modified dates. I’ll reproduce the supplied problem case, trace each outbound and inbound API request, and compare the payloads against the integration database and datatable mappings to identify where values are transformed, omitted, or assigned to the wrong field. I’ll also inspect webhook event handling, filtering, retries, and update direction to catch duplicate or stale updates. I’ll verify date formats, timezone handling, null values, Unix timestamps, and whether modified-date events are triggering unintended overwrites. Any incorrect non-date fields found during the audit will be documented as well. After isolating the defects, I’ll apply focused fixes, test both sync directions with the provided accounts, and confirm the corrected records in Total Synergy and Trello. I’ll keep the changes limited to accuracy rather than performance improvements and provide a concise summary of the root causes and fixes. Is the existing problem case reproducible with one specific Total Synergy record and Trello card? Muhammad Saad

Hi, Date drift in API synchronizations is usually caused by small inconsistencies in field mapping, timezone handling, or update ordering rather than the API calls themselves. Finding the exact point where the data diverges is the key step before making any changes. I would audit the existing sync flow by tracing the affected records through the API requests, database mappings, and webhook events to identify where incorrect values are introduced. The fix should focus on correcting the source of the mismatch rather than adding extra sync logic that could create more conflicts. One area I would check early is whether Total Synergy and Trello are storing or returning date fields with different timezone assumptions, as this can create recurring discrepancies even when the mapping looks correct. Are the incorrect dates consistently shifted by a pattern (for example, hours/days difference), or are they being replaced with unrelated values? That distinction usually points to different root causes. If you can provide one or two example records where the dates drift, I can trace the sync path and identify the likely failure point.
