Why WhatsApp Template Messages Fail Silently and How to Prevent It

·2 views

A WhatsApp template send can return a success response with a message ID yet never reach the customer, because Meta accepts the request first and reports delivery later through a status webhook. Common production causes include header media that Meta cannot fetch, a parameter count that does not match the approved template, and a copy-code button sent without its coupon. Developers are advised to build sends from the template definition, refuse to send when values are missing, and upload media to obtain an ID rather than relying on public links. Carousel templates are a particular trap, since their header media sits inside each card and is missed by code that only checks top-level components. Until a delivery status arrives, an accepted message should be treated as unconfirmed.

Batch API Costs Can Double: Six Pitfalls in a .NET OpenAI Batch Pipeline

A developer explains that OpenAI's Batch API offers half-price processing for non-urgent bulk work, but the surrounding application code can erase those savings. The article describes six common mistakes in a .NET 10 batch pipeline, including duplicate batch submissions after a crash. It recommends tagging each batch with metadata and saving state before every provider call so restarts don't resend work. It also advises sorting failures so only transient errors are retried, with a capped attempt budget, and notes that output lines can return out of order and may be missing. The piece is promotional, pointing readers to a paid course for the full working project.

Orquesta Lets Teams Collaborate on Environments via Agent Prompts, Without SSH

Orquesta was built to avoid the risks of sharing SSH keys, which expose entire filesystems and secrets, and which non-technical teammates cannot easily use. Instead, a local agent runs on the machine hosting the environment and executes prompts submitted from a web dashboard. The agent uses the Claude CLI, streams its output live, and commits every change to git, so no shell access is shared with users. Team members receive role-based permissions such as Admin, Developer, Reviewer, and Observer to control who can submit or only view work. The workflow lets a non-engineer request a change that the agent implements on a branch and submits as a pull request for review.

PostgreSQL JDBC driver could silently downgrade SCRAM channel binding, fixed in 42.7.12

CVE-2026-54291 affects the PostgreSQL JDBC driver when configured with channelBinding=require. Under that setting, the driver could fall back from SCRAM-SHA-256-PLUS to plain SCRAM-SHA-256 without informing the application. The connection could succeed while the client assumed the stronger protection, which is tied to the TLS tunnel, was in effect. The fix is included in JDBC driver version 42.7.12. Administrators are advised to upgrade all runtimes and bundled drivers and to verify the negotiated authentication mode through integration testing and logging.
