Character Limits and Data Types

Mapp Intelligence enforces a small set of size and character limits on every tracking request. The iOS SDK passes user‑supplied values through verbatim — these limits apply on the server side, so it is your responsibility to stay within them when populating MI…Parameters objects.

Encoding

All tracking requests use UTF‑8.
Input is case‑sensitive.

Request and parameter limits

Limit	Value
Maximum size of one tracking request	7 KB
Maximum text parameter length	255 characters per value
Multi‑value text parameters	Each value can be up to 255 characters; each scalar is stored as one parameter on the server. See Multi‑value parameters.
Numeric ("figure") parameter range	`decimal(12, 2)` — ten digits before the decimal point, two after (range −9 999 999 999.99 to 9 999 999 999.99).

Filtered characters

Mapp Intelligence automatically removes or normalises the following characters during ingest:

Control characters in the range 0x00–0x1f
Single quote (') and double quote (")
<, >, \
Non‑breaking space (0xA0) is converted to a regular space
Multiple consecutive spaces are collapsed to a single space
Leading and trailing spaces are removed

If you need to keep specific punctuation (for example in product names), URL‑encode the value before passing it to the SDK.
