Frequently Asked Questions
What is the AWS API 1104 endorsement exam and who is it for?
The AWS API 1104 Endorsement is a code-book exam administered through the AWS CWI program. It validates an active CWI or SCWI's ability to apply API 1104:2021 (Welding of Pipelines and Related Facilities, 22nd Edition). Pipeline construction and integrity inspectors take it to qualify for pipeline projects that require API 1104 expertise.
How many questions are on the API 1104 endorsement and how long is the exam?
The exam has approximately 60 multiple-choice questions with a 2-hour time limit. That averages 2 minutes per question — reasonable for an open-book exam that requires frequent code lookups. A passing score of 72% is required, so candidates can miss roughly 16 questions out of 60.
Is the API 1104 endorsement open book?
Yes. The exam is open book. Candidates may rely on memory and experience, use the electronic copy of API 1104:2021 provided on the testing computer, or bring their own bound printed copy. Tabbing your printed standard for fast lookup of Sections 5, 6, 9, 10, 11, and Annex A is a major time-saver.
How much does the API 1104 endorsement cost in 2026?
AWS list pricing is $445 for AWS members and $540 for non-members. AWS individual membership ($90/year) typically pays for itself if you are taking any endorsement. You will also need a copy of API 1104:2021 if you do not already own one.
Do I need to take the API 1104 endorsement before or after my CWI exam?
You must already hold an active CWI or SCWI to register for the API 1104 endorsement — it is layered onto your existing credential, not a stand-alone certification. Many candidates take it shortly after passing CWI Part C with API 1104 to consolidate their pipeline focus.
What is the hardest part of the API 1104 endorsement exam?
Section 9 acceptance standards is where most candidates lose points — the dimensional limits for porosity, slag (ESI), IP/IPM, IC/BT, undercut, and the AOI rule are easy to confuse. The Annex A in-service welding rules (burn-through risk, HAZ hardness, temper-bead) are also commonly missed by candidates without operating-pipeline experience. Drill Section 9 charts and Annex A hardness/temper-bead rules before exam day.
