Solidgate rail-short is not Braintree first-hold short
On one Solidgate rail cut, compute (requested auth $ − partial auth $) ÷ requested auth $ × 100. That is SG rail-short %.
Pair: Partial-auth gap on Payments. Braintree twin: first-hold short. Settle twin: partial-settle.
What you type
Requested auth $ — Dollars Solidgate asked the issuer to authorize on the cut.
Partial auth $ — Dollars actually approved as a partial authorization in that cut.
Gap $ = requested − partial. SG rail-short % = gap ÷ requested × 100. Fat SG rail-short % usually tracks issuer or cart rules on that rail — chase the rail; never invent an SG rail-short chip.
What not to do
Do not invent SG rail-short %. Do not load a Braintree or Authorize.net partial-auth export into Solidgate fields. Do not treat a later settle short as a first-auth under-approval. Do not blend MIDs when one Solidgate rail owns the gap.

Procedure
- Type requested auth $ and partial auth $.
- Read gap $ and SG rail-short %.
- Chase issuer / cart rules when SG rail-short % is material.
Failure modes
- Inventing SG rail-short %.
- Dumping a Braintree or Authorize.net partial-auth file into Solidgate rail ask / hold fields.
- Treating a later Solidgate settle short as a first-hold short.

FAQ
- Is this Braintree first-hold short?
- Different gateway book. [Braintree first-hold short](/manuals/braintree-partial-auth-gap) reads Braintree vault ask vs approved hold. Here you only score Solidgate rail under-approvals on a Solidgate cut.
- Is this Solidgate partial-settle gap?
- Settle grain, not first auth. [Partial-settle gap](/manuals/solidgate-partial-settle-gap) is partial-settled $ ÷ captured $. This page starts at requested auth $ vs partial auth $.
- What SG rail-short % should I invent?
- None. Pull requested auth $ and partial auth $ from the same Solidgate rail cut.
