What It Is

FBPostback is a Facebook Conversions API postback middleware built for media buyers, agencies, and Pay-Per-Call marketers. It connects call-tracking platforms such as Ringba, Retreaver, or any other platform that supports webhook/postback URLs with Facebook/Meta CAPI, sending events in real time when inbound calls or phone conversions occur. Its goal is to address common issues in phone lead advertising, such as lost attribution, incorrect CAPI setup, and delayed postbacks.

Core Features and Data Scale

The product workflow is straightforward: first connect your call-tracking platform, then enter your Facebook Pixel ID and access token, and finally let the system send incoming calls or converted calls back to Facebook. Its payload helper can validate configurations and assist with troubleshooting before launch. The site states that it serves 500+ media buyers, has processed 10M+ API calls, and offers 99.9% uptime. On privacy, it says personal information such as phone numbers, names, and locations is hashed with SHA-256 before being sent, and that it complies with GDPR/CCPA while not storing or selling data.

Pricing and Trial

FBPostback uses a monthly subscription model with included API call quotas. Starter costs $29.99/month and includes 30,000 API calls, making it suitable for roughly 500 calls/day. Growth costs $44.99/month and includes 75,000 calls plus priority support. Pro costs $69.99/month and includes 300,000 calls, priority support, and an advanced API usage analytics dashboard. All plans come with a 7-day free trial with no credit card required. If you exceed the included quota, tracking does not stop; instead, overages are billed at a small per-call rate.

Pros and Cons

The main advantage is its focused positioning: it is especially well suited to Facebook campaigns where phone calls are the core conversion goal. Setup is relatively easy, with integration via copied URLs and API tokens. Pricing and call quotas are transparent, and the free trial lowers the cost of testing. Its limitations are that it is not a general-purpose SEO or marketing automation tool, so its use case is fairly narrow. Public materials do not specify payment methods, support channels, SLA details, team permissions, or data retention policies. Current prebuilt templates explicitly mention Ringba, while more templates are still planned.

Who It’s For and Access from China

FBPostback is suitable for solo media buyers, vertical specialists in call-based lead generation such as insurance, Pay-Per-Call agencies, and performance marketing teams managing multiple campaigns and pixels. Access from China cannot be confirmed from the available information. Since the tool depends heavily on Facebook/Meta, relevant ad accounts, and overseas call-tracking platforms, China-based teams may also need to consider network connectivity, foreign-currency payments, and the availability of the Meta ecosystem. Alternatives to compare include Meta Conversions API Gateway, Stape, Zapier/Webhooks, self-built CAPI postbacks, or Facebook integrations provided directly by call-tracking platforms.
