Ask a D2C founder how many third parties their customer data touches and most will guess low. Ask them to actually list every tool wired into their store and the number usually doubles. This gap matters under the DPDP Act, because the Act makes you, the merchant, a "data fiduciary" responsible for every one of those flows, whether you remembered it exists or not.
Here is what a typical Indian D2C Shopify stack actually looks like, tool by tool, and why each one puts you on the hook.
Meta Pixel
If you run Facebook or Instagram ads, the Meta Pixel on your store is sending event data, pages viewed, products added to cart, purchases completed, back to Meta, often tied to identifiers that can be linked to a specific shopper. You installed it for retargeting. Under the Act, you are the one responsible for disclosing that this flow exists and getting consent for it, not Meta.
Klaviyo or any email and SMS tool
Your email platform holds names, email addresses, phone numbers, and purchase history, and uses that to send abandoned cart emails, promotional campaigns, and post-purchase flows. That is personal data sitting with a processor you chose. The shopper needs to know this tool exists and what it does with their information.
WhatsApp via a business solution provider
Order confirmations and abandoned cart nudges sent over WhatsApp usually go through a business solution provider, a layer between your store and WhatsApp itself. That provider sees the shopper's phone number and the content of what you send them. It is a distinct processor in your chain, separate from WhatsApp, and separate from your store.
Your 3PL or logistics partner
Every order you fulfil hands a shopper's name, address, and phone number to a delivery partner. This is unavoidable for a physical product business, but it is still a transfer of personal data to a third party, and it belongs on your list.
Review apps, like Judge.me
A review app typically has access to a customer's name, email, and order history so it can request and display reviews. It is easy to forget this tool is even installed months after setup, which is exactly why it gets missed on self-made lists.
Razorpay and GST invoicing tools
Payment and invoicing tools handle some of the most sensitive data in your stack, names, addresses, and payment details, even when the card data itself is tokenised elsewhere. They are processors too.
Why the full list matters more than any single entry
The risk is not any one of these tools individually. Payment gateways and logistics partners are fundamental, legitimate parts of running a D2C business. The risk is a partial list. If your privacy notice names three tools and your store actually uses seven, the notice is wrong, and a notice built on a wrong list cannot support real consent either.
The only durable fix is to find the complete list from the store itself, not from memory. This is the first and most mechanical of Consent Jet's four functions: it scans your store to find every third-party tool actually sending or receiving customer data, so that the notice and consent banner built on top of it are built on the full picture rather than a guess.
