🔗 Your tools don't talk to each other? I connect them so your data flows on its own
You copy your orders into a spreadsheet, your leads into your CRM, your payments into your accounting… Every manual re-entry wastes time and creates errors.
I build the custom integration that links your tools: reliable, secure, automatic, and built to last.

⭐ MY RECOMMENDED OPTION
🔗 Additional connected tool (+€60)
Most businesses use more than two tools. Adding a third tool to the same flow (e.g. store → Google Sheets and Slack) multiplies the time saved at a minimal cost.
📋 WHAT DO I NEED?
| Information | Example |
|---|---|
| 🔀 The desired flow | "When X happens in tool A, I want Y in tool B" |
| 🧰 The tools involved | Names, and your subscription plan (some plans limit API access) |
| 🧩 The data to transfer | Useful fields: name, email, amount, product… |
| 🔐 Secure access | Collaborator access or a limited API key (I guide you step by step) |
| 🧪 Examples | An order, a lead or a test row |
🔁 REVISIONS AND SCOPE
| ✅ Included | ➕ Option or custom offer |
|---|---|
| 2 rounds of revisions on the planned integration | New tool or new flow |
| Fixing any bug within the delivered scope | Sync in the other direction |
| Adjusting the transferred fields | Complete change of behavior after approval |
| — | Adapting to a future change in a third-party tool |
Revisions related to the items included in the order are included. Any new feature or major change of scope may require an option or a custom offer.
ℹ️ The integration depends on your tools' APIs: if a function isn't available in their API or in your subscription plan, I'll tell you before starting and we'll find an alternative.
✅ WHY CHOOSE THIS SERVICE?

| 🔐 Security | Limited access, keys never exposed, best practices |
| 💸 No per-task cost | No automation subscription that grows with your volume |
| 📦 Source code delivered | You stay the owner and independent |
❓ FREQUENTLY ASKED QUESTIONS
Can my tools be connected?
If the tool has an API or webhooks, yes in the vast majority of cases. Send me their names before ordering and I'll confirm feasibility.
Why not Zapier or Make?
These tools are great for simple cases. A custom integration is better when the logic is complex, the volume is high (no per-task cost) or you want full control.
Do I have to give you my passwords?
No, never. I'll guide you to create collaborator access or a limited API key that you can revoke at any time.
