Session Webhook

<p class="slate-p " >This endpoint enables a merchant to configure a webhook URL for receiving real-time notifications related to user sessions. By providing the Billink username, ID, and the desired webhook URL, merchants can seamlessly integrate session updates into their systems and ensure timely, automated handling of relevant events.</p><p class="slate-p " ></p><p class="slate-p " ></p>

Session Webhook Instellen

<p class="slate-p " >This endpoint allows a merchant to disable a previously configured session webhook. Once the Billink username and ID are provided, the associated webhook will be removed, stopping any further session-related notifications from being sent to that URL.</p><p class="slate-p " ></p><p class="slate-p " ></p>

Session Webhook Uitschakelen

<p class="slate-p " >The <strong class="slate-bold">Order Webhook</strong> notifies your system about important events in the order lifecycle.</p><p class="slate-p " >This allows your platform to react in real time — for example, when an order is placed, partially paid, fully paid, credited, or put on hold.</p><div style="width:100%;

Implementatie tips

<p class="slate-p " >To clearly display Billink at checkout, it is important to mention that the customer can pay afterwards. This is central to how we communicate as a company. Always use the following text next to or behind the Billink logo:</p><ul class="slate-ul " ><li class="slate-li " ><div style="position:relative">Pay afterwards with Billink</div></li><li class="slate-li " ><div style="position:relative">Pay later with Billink</div></li><li class="slate-li " ><div style="position:relative">Pay afterwards</div></li></ul><p class="slate-p " >These formulations are clear and directly inform the customer about the possibility of paying afterwards via Billink. It is essential to always display these texts at checkout.</p><div style="text-align:left"><img src="https://cdn.billink.nl/assets/dedicated/branding/checkout_voorbeeld_1.png" style="
