One or more computer processors submit the captured one or more API calls to a blockchain ledger. One or more computer processors detect a system failure during the service provision. One or more computer processors extract the submitted one or more API calls from the blockchain ledger. Based on the extracted one or more API calls, one or more computer processors identify a problematic system associated with the system failure. ## Claims ### Claim 1 A method comprising: capturing, by one or more computer processors, one or more application programming interface (API) calls associated with a service provision; submitting, by one or more computer processors, the captured one or more API calls to a blockchain ledger; detecting, by one or more computer processors, a system failure during the service provision; extracting, by one or more computer processors, the submitted one or more API calls from the blockchain ledger; and based on the extracted one or more API calls, identifying, by one or more computer processors, a problematic system associated with the system failure. ### Claim 2 (depends on 1) The method of claim 1, wherein identifying the problematic system further comprises: performing, by one or more computer processors, a root cause analysis of the system failure during; generating, by one or more computer processors, a report, wherein the report includes the root cause analysis, the problematic system, and at least one corrective action; and submitting, by one or more computer processors, the report to the blockchain ledger. ### Claim 3 (depends on 2) The method of claim 2, further comprising, notifying, by one or more computer processors, an owner of the problematic system. ### Claim 4 (depends on 1) The method of claim 1, further comprising: retrieving, by one or more computer processors, a smart contract associated with the problematic system and the service provision; receiving, by one or more computer processors, one or more API calls associated with the problematic system; and based on the smart contract, generating, by one or more computer processors, a dummy response to the one or more API calls associated with the problematic system. ### Claim 5 (depends on 4) The method of claim 4, further comprising, submitting, by one or more computer processors, the one or more API calls associated with the problematic system to the blockchain ledger. ### Claim 6 (depends on 4) The method of claim 4, further comprising: processing, by one or more computer processors, one or more unprocessed call details associated with the one or more API calls associated with the problematic system; and parsing, by one or more computer processors, the one or more unprocessed call details into one or more actions, based on the smart contract. ### Claim 7 (depends on 1) The method of claim 1, further comprising, prior to detecting the system failure, detecting, by one or more computer processors, a cloud service provision workflow execution. ### Claim 8 A computer computer program product comprising: one or more computer readable storage media and program instructions collectively stored on the one or more computer readable storage media, the stored program instructions comprising: program instructions to capture one or more application programming interface (API) calls associated with a service provision; program instructions to submit the captured one or more API calls to a blockchain ledger; program instructions to detect a system failure during the service provision; program instructions to extract the submitted one or more API calls from the blockchain ledger; and based on the extracted one or more API calls, program instructions to identify a problematic system associated with the system failure. ### Claim 9 (depends on 8) The computer program product of claim 8, wherein the program instructions to identify the problematic system comprise: program instructions to perform a root cause analysis of the system failure during; program instructions to generate a report, wherein the report includes the root cause analysis, the problematic system, and at least one corrective action; and program instructions to submit the report to the blockchain ledger. ### Claim 10 (depends on 9) The computer program product of claim 9, the stored program instructions further comprising, program instructions to notify an owner of the problematic system. ### Claim 11 (depends on 8) The computer program product of claim 8, the stored program instructions further comprising: program instructions to retrieve a smart contract associated with the problematic system and the service provision; program instructions to receive one or more API calls associated with the problematic system; and based on the smart contract, program instructions to generating a dummy response to the one or more API calls associated with the problematic system. ### Claim 12 (depends on 11) The computer program product of claim 11, the stored program instructions further comprising, program instructions to submit the one or more API calls associated with the problematic system to the blockchain ledger. ### Claim 13 (depends on 11) The computer program product of claim 11, the stored program instructions further comprising: program instructions to process one or more unprocessed call details associated with the one or more API calls associated with the problematic system; and program instructions to parse the one or more unprocessed call details into one or more actions, based on the smart contract. ### Claim 14 (depends on 8) The computer program product of claim 8, the stored program instructions further comprising, prior to detecting the system failure, program instructions to detect a cloud service provision workflow execution. ### Claim 15 A computer system comprising: one or more computer processors; one or more computer readable storage media; program instructions collectively stored on the one or more computer readable storage media for execution by at least one of the one or more computer processors, the stored program instructions comprising: program instructions to capture one or more application programming interface (API) calls associated with a service provision;
