WhatsApp error 132005: Template Hydrated Text Too Long

Code 132005 means that once your parameter values were substituted into the template ("hydrated"), the resulting text exceeded the length the platform allows. Template bodies are limited to 1,024 characters and headers to 60, and those limits apply to the final rendered message, not just the approved skeleton. Long variable values, especially product names, addresses, order lists, or user-generated text, push the result over the line.

The official message calls it "translated text", and Meta's solution text points at checking translations in WhatsApp Manager; in practice the trigger is almost always the values you supply rather than the translation itself. It will fail for every recipient who receives the same long value and succeed for others, which makes it look intermittent.

Approval status, language, and parameter count are all fine when you see this code; the content is simply too long after substitution.

Enforce per-parameter maximum lengths in your code, derived from the template's static length and the 1,024-character body and 60-character header limits, so values are trimmed before the API call. Keep templates concise so variable values have headroom, and test with the longest realistic data from production rather than short sample strings. Body, header, and button length ceilings are listed in the template limits table, and the template checker flags over-length content before submission.
